A good way to pull through the grind to 70 w/o going crazy amounts of oom is to just focus on damage/int/spirit gear, now I haven't had to do this grind in a long while as boomkin but what I'm thinking now will get you through is this.
A higher intellect obviously is going to help your dreamstate on top of your mp5 already. Intellect when talented adds back to your spell damage which is good, plus having more int means less down time with mana issues. Spirit is spirit, if you're spec'd Imp Moonkin it will obviously add damage and give you more mp5.
I would also glyph with moonfire and insect swarm. You won't be raiding so you're not going to need the -% chance to hit from mobs for your tanks and your insect swarm is going to push out more damage. Plus having that moonfire glyph is going to increase your over time damage. I would try a spell rotation something like this: Pull with either starfire or entangling roots. If you pull with starfire, root afterwards to keep yourself from getting hit, and then dot it up with MF/IS. Most mobs in that level range have about 3-6k health, the tic damage you give them should be more than enough to drop them down far enough to hit them with a wrath or another starfire.
This is more of a patient way to kill them, but trying to be more mana conservative. Just consider yourself like a lock.
Another good way to get through w/o going oom as well is to build a set of spirit gear. Just normal greens that offer great amounts of spirit. Once you build up a spirit set that gives you a decent amount of spirit write a macro or use outfitter to make a quick click button so you can pop it on and use innervate. Obviously if you do this you're goal is going to make your mana pool last 6 minutes.
Also, going 5/5 furor will help giving 10% more intellect in boomkin form.
All of this may or may not fix your problems with going oom but you're going to run in to times where you need to drink to mana up.
I'll link you guys my armory so you can see how I have my gear set up. Mind you I may be in my boomkin pvp spec and in my pvp gear (resto s2 ftl). But I'll try to get in raiding gear before I head to work today.
Edit: I totally didn't link you guys my armory....
This is it. Edit Again: In my pve gear and with my spec I linked earlier I'm hitting single target dps for a max of around 2000-2100 dps and 1400 is generally the lowest dps I get. My gear isn't all that spectacular a majority of it is either badge/za/kara. Two pieces are from TK and my Boots are from BT. So getting crazy good gear isn't a necessary thing if you know how to push your spells and stack your stats correctly. Talented and raid buffed my Starfire crit chance is usually between 43-44%, which I rely heavily on for damage.
