A few things:
Your gun is too fast for a BM hunter. Get a gun that is closer to the 2.8 mark or so. It will help your dps more than you think. Right now, with all of your talents and your ammo pouch and such, you're clipping your auto-shots. If you get a gun with a speed of 2.7 or 2.8, you'll be getting the full effect of the gun's damage.
You're too worried about stamina. I know you think your gear doesn't merit better enchants yet, but most of the attack power and agility enchants are very easy and relatively cheap. 26 attack power to gloves, for instance, only takes a little bit of arcane dust. Right now you have more health than I do, and I'm basically completely decked out in epics.
Don't worry about socket bonuses unless they're actually worth it. The one on your helm almost is, but if you think about it, you could use 3 +16 AP gems there, which would come out to 48 AP, whereas right now you have 32 AP between the gems and the bonus. MP5 is nice, but unnecessary unless you're raiding. Even then, some mana potions and/or a shadow priest will go a long way. Your belt is another place where you could easily lose the socket bonus. Like I said, you don't need so much stamina. If you're running heroics, my opinion is that another 500 health won't do anything for you. If you have a mob beating on you and feign is down, chances are good that you're dead anyway. And your leggings - why would you want a dodge rating socket bonus? Do 3 +16 AP gems in there. Or 3 +8 Agi gems - get yourself a little more crit.
Back to enchants - your disco axe is actually a pretty decent weapon. It will last you until you get one of the following: Legacy from Kara, the Sonic Spear from Slabs, or the rep weapon from Honor Hold (I'm horde, so I don't know what you guys call it)(I know there are other decent weapons out there, but those are the most common and probably the easiest to get - except I've never seen the Sonic Spear or Legacy drop, but that's besides the point). Put savagery on it.
Finally, level up your leatherworking. I used to not be a believer, but the Ebon Netherscale set is very good. It's a pain to make, but it has lasted me a long time.
BM hunters can do some crazy dps, and they are ridiculously easy to do dps with. I don't know what I would peg you at, but you should be a little higher. Your gear isn't bad, it just needs the tweaks I've mentioned.
Edit: To Altrizia - your gear is good, so I don't completely understand why you aren't doing more dps than you are - the two obvious things I see are with your spec. I'm not trying to tell everyone to go out and do the cookie-cutter BM build, but if you want to max your dps, move 5 points from endurance training to improved aspect of the hawk and 2 points from spirit bond to animal handler. This would require you to make some other changes, but it is worth it. Also, as I mentioned above, the disco axe is a good weapon. Don't hold out for the sonic spear because it has a nasty habit of never dropping. For me, anyway. But I think the rep weapon from Thrallmar/Honor Hold is better.
