This post is not my own work. It was written by Scout, from the Skywall server, and is currently stickied at the Blizzard hunter forums. You can find the original here.
I'm not saying I agree 100% with it, particularly the priority of learning certain items, but it's a decent guide overall and I'm too lazy to write my own. (What? I wrote the last 3 pages worth of content. I'm tired!)

It is a fantastic thread, and it covers everything you will ever need to know through level 59 and then some. But once upon a time, I walked through the portal at the bottom of Blackrock Depths into Molten Core, proudly clad in my Dire Maul blues, a veteran of dozens of Stratholme and Scholomance runs, bearing an ammo pouch full of the finest Thorium Shells on the planet ... and I did not have the foggiest idea of what I was getting into.
Obviously, the learning curve involved a lot of repair bills.
This guide basically represents all the things that I try to teach our new hunters. Before you walk into Molten Core, you should have your Freshman level down. By the time you hit your first boss, understand the Sophomore concepts. Junior and Senior levels will get you past Ragnaros and into Blackwing Lair respectively. Graduate level is for hunters who think that doing a good job isn't good enough, and who don't mind the extra costs for repairs and pet food.
And always, always remember, skill is your most important asset. Spec is not skill. Gear is not skill. Potions and mods and macros are not skill. Skill is skill. Get skilled and stay skilled. Y vayan con Dios.
FRESHMAN LEVEL
1. Do not pull aggro. Feign early. Feign often. Do not go nuts with burst damage when there is 1 sunder on the mob. For !&$%'s sake, your DPS doesnt have to be 98% of the theoretical upper limit as long as you don't wipe the raid.
2. Don't suck up healing if you can avoid it. There are lots and lots of obvious exceptions, but as a general rule, you shouldn't be taking much damage compared to the rest of the raid. You wear mail. You stand at range. Bring bandaids and take care of your own damn health.
3. Die if you have to. Dead hunters deal no DPS, but they don't wipe raids, either. If you pull aggro and your FD resists, chances are you're taking one for the team. Run TOWARD the tank. Remember Disengage? Spam it and you might possibly live. If not, then learn to cope with the shame of your repair bill. You earned it.
4. Get healthy. In many fights, you're going to take damage due to AOEs or randomly targeted effects. In general, you are low man on the totem pole when it comes to heals. To a first approximation, the best thing you can do is get stamina gear. If you are setting foot in MC/AQ20/ZG for the first time ever, 3200 health is a good target number. If you're setting foot somewhere tougher, 4000. You can never, ever have too much health.
5. Repair and resupply. Do not show up for a raid with less than a full bag of ammo. Do not show up for a raid with less than 100% durability. Titan Bar will track durability and ammo, and it also has an addon that prompts you to fix everything you're holding every time you visit a merchant. It also has a bunch of other assorted goodies, too. http://www.curse-gaming.com/en/wow/addons-860-1-titan-panel.html
SOPHOMORE LEVEL
6. Learn the 10-second rotation. Start an Aimed Shot immediately after an Auto Shot. Multishot when the cooldown is up. Wait for Aimed Shot to cooldown. Wait for an Autoshot to fire. Repeat. That's all there is to it, and in most fights, this will maximize your DPS. And yeah, toss in Feign Death and Rapid Fire whenever they're up.
7. Stand at range. Several bosses have AOE damage spells, curses, debuffs, or fears. Many of these have a 30 or 40 yard range. With Hawkeye, you have a 41 yard range. Shoot from 40.9 yards. The RangeHelp mod helps greatly with this. http://www.curse-gaming.com/en/wow/addons-1549-1-rangehelp.html
8. Know your specs. If you want to maximize raid DPS, the cookie-cutter spec is 5/31/15. If you are wearing blues and you're new to raiding, this is the simplest, highest-DPS build out there -- especially if you take into account the DPS boost that your party members get from Trueshot Aura. That said, 5/31/15 that is a very one-dimensional spec, and it doesn't solo or PvP well. Most raiding hunters actually use a 0/21/30 spec, myself included. Your DPS suffers a little comparatively, but you're vastly more effective in every non-raid situation. This is not to say you can't have some other kind of spec and still raid, but don't kid yourself that your raid DPS is going to top the charts. For further reading, Rainfalle has written a nice analysis of talents. http://forums.worldofwarcraft.com/thread.aspx?fn=wow-hunter&t=913006&p=1&tmp=1#post913006
9. Keep Hunter's Mark up. On bosses, every hunter in the raid is going to be focusing fire on a single target. Rank 4 Hunter's Mark is 110 RAP per hunter. With 5 or so hunters in the raid, the added DPS from a Hunter's Mark is on par with the highest ranks of Corruption or Shadow Word: Pain and costs a fraction of the mana. Do not let it drop.
JUNIOR LEVEL
10. Get resist gear and know when to use it. Also, keep it repaired, because its pretty embarrassing to reach Ragnaros and realize that all the Fire Resist gear in your bag is busted. Trust me: I speak from experience. To begin with you'll only need Fire Resist, and only for certain encounters. Later, you'll need Nature and Frost for AQ40 and Naxx respectively, but you can burn those bridges when you come to them. http://www.wowwiki.com/Mail_Resist_List
11. Feign and Drink. During boss fights, you're better off drinking mage water rather than waiting for mana regen while autoshotting. Judgment of Wisdom or not, drinking is more effective than autoshotting. Besides, drinking in combat reminds all the other casters of the fundamental superiority of the hunter class. Have fun rubbing their noses in it. Heck, make a macro that goes "/y Look at me! I'm DRINKING WATER and YOU AREN'T! BWAHAHAHA!" Just don't expect to get a heal. Ever again.
12. Get +hit gear. For PvP encounters, you want 5% of hit gear and/or abilities. For instances, the generally agreed-upon number is 9%. That means that in addition to resist gear and DPS gear, you should have a set of Tranq Shot gear too. Also, if you are Tranqing, work out your rotations with your fellow hunters (and always assign a backup in case of disconnection or death), and get a damn mod to announce it. http://www.curse-gaming.com/en/wow/addons-1718-1-simpletranqshot-187.html
13. Learn when to use Arcane. In some fights, Aimed Shots are impossible to cast because of constant interruption by damage auras or AOEs. In these cases, Arcane Shot is better for you than Aimed. Again, you have to know the encounters. Sorren's Hunter Timers will add an Aimed Shot casting bar to your UI, which will help you get a feel for these interruptions. http://www.curse-gaming.com/en/wow/addons-2595-1-sorren39s-hunter-timers.html
14. Learn when to use Aspect of the Wild. In ZG and AQ20, Nature Resist is helpful. In AQ40 it is absolutely necessary. Aspect of the Wild is 60 NR to everyone in your party, which translates to roughly 15% damage reduction all around. Use it.
SENIOR LEVEL
15. Scattershot and Feign Death/Freeze Trap. Useless in MC but occasionally useful in BWL. Very useful in ZG and AQ20. You can lock up a mob for over a minute with good timing, the right talents, and a little luck. Especially in 20-man instances, CC is your friend. As a side note, General Rajaxx can be freeze trapped, believe it or not.
16. Pet pull. In MC, there are 2 bosses that absolutely should be pet pulled. In BWL and AQ40, pet pulling is not a bad option for some trash mobs and/or bosses, depending on your guild's strategy. Pet pulling also works nicely for clearing towers/bunkers in AV, too, if you have a cat. Learn Eyes of the Beast, and experiment with Stay/Follow and Aggressive/Passive. Also, get a feel for the range where your pet despawns.
17. Learn when to use Serpent Sting. Serpent Sting is not a bad investment of mana. However, it is a terrible investment of a debuff slot. If there are slots open (or if you're fighting something Nature vulnerable in BWL) feel free to cast Serpent. If the mob's debuff bar is full, then don't. Serpent Sting is crappy compared to almost every other debuff.
18. If you haven't learned to kite, learn to kite. It's not that useful in MC, but in BWL, there are at least 3 different mobs that you can and should be kiting while the rest of the raid kills things. Kiting is also a necessary skill for your epic bow quest. If you don't know how to kite, go to the Barrens (or equivalent) and try to kill a level 15 mob with Rank 1 Arcane only. If you can do that, then go to southern Dustwallow Marsh and kill Emberstrife. His cave is circular with a nice ramp to jump off of, he is just a tad bit slower than Cheetah, and no one ever goes there. It is perfect for kiting practice. By the way, if you're going to be kiting a lot, keep a set of the AB boots or put a Run Speed enchant on a spare pair of something or other. Flame Walkers are my personal choice for the enchant. http://www.thottbot.com/?i=39132
GRADUATE LEVEL AND BEYOND
19. Know when to pull aggro and die. Once in a while, the $!@% hits the fan. A tank forgets his Onyxia Cloak. A healer DCs in the middle of combat. A mage gets a Power Infused ZHC Fireball crit on a vulnerable target and gets instantly wtfbloodypulped by a pissed-off Wyrmguard. We have the 3rd highest AC on either faction, and we are often in the best place to catch aggro. If something big and nasty is rampaging through your clothies, pull aggro with burst damage and Distracting, and enjoy your brief life as a tank. Even if you have Deterrence, most raid trash is going to kick your *** inside 20 seconds. But sometimes that's all the time the raid needs to get it together.
20. Know how to pull aggro and live. Some trash mobs are Wingclippable. If one of them is loose, or if you just feel like causing general panic amongst your healers and tanks, pull aggro, Wingclip, and strafe. If you do it right, you'll still get hit when you're in range, but you'll be in range less than 10% of the time. Because of this, a kite-tanking hunter actually takes less damage than a tanking warrior. The downside is ... there ain't many Wingclippable mobs. And you shouldn't generally expect heals if you try this. As a sidenote, kite-tanking works great on all those Lieutenants and Flight Masters in AV.
21. Use your pet. Kiava has written a fantastic guide to pet use in instances. I have nothing to add except that if you've read this far in my thread, go read her thread. It's good stuff. http://forums.worldofwarcraft.com/thread.aspx?fn=wow-hunter&t=1066425&p=1&tmp=1#post1066425
22. Maybe Marksman spec isn't that special after all. At Tier 3 levels of agility, a Survival build may overtake a Marksman build for DPS, but the jury is still out. Alternatively, at least one hunter has made the case that some points in Beastmastery and a "competently used pet" is actually the best raid DPS. You can play with the math yourself in Rooke's spreadsheet. http://forums.worldofwarcraft.com/thread.aspx?fn=wow-hunter&t=1066563&p=1&tmp=1#post1066563
