im considering coming back to wow after a 4 month break, and i want to level a human rogue. dont have any boa or anything like that. IF i do, what spec should i level as and how should i level (dungeon BG quest gathering etc)?

I use to play WoW and had a rogue. I level by using Combat to lvl 32-33 and switched to Subtley. Combat allows you to use less energy and gain energy faster. At 32, Subtley becomes best due to its higher hitting. Level by questing and queing in instances.
