Lvl 36 and working Darnassus Faction

Ok so I'm lvl 36 and I've completed all the quests I can find and get for Darassus Faction, I currently am at 12346 into a 21000 xp grind in Revered. I'm trying to get to exhaulted before i turn lvl 40 so i can get my kitty mount. Anyone know a place I can get some more faction before 40? Any information appricated and Thanks :D
