And once you hit 48-50 or so, you should be able to farm the Deadwood Furbolgs. (not sure, though, I haven't leveled a priest yet, don't know how well they solo...)
Check out this link for where they're at in Felwood.

They've dropped a ton of Mageweave and silver for me. And they raise your Timbermaw reputation. Just becareful of wandering gankings and Allaiance. It is a quest spot so, it'll support usually 2 people at a time I'd expect. But they respawn fairly quickly, so it's all good. Also, be aware that there are a few mobs that spawn in the area that are wanderers and walk in a huge circle around the place.
Goodluck and if you're on Dragonmaw, you won't even see me before it's too late ;)
