Level.
Unless you are trying to twink for a low level bg group, just level. Honestly, gear really is not going to matter to you. I could probably level a hunter from 1-70 with no spec and some grey gear. Until gear really does matters, just pick up stuff as you go with the right stats. Sta, Agi, Int. If you want to spend money, do it on a nice ranged weapon, or a nice heavy 2 hander with good stats.
