Heh, I've already done my share of swimming around Theramore bay. Stupid reclusive Nat Pagle...
I have loremaster on my main, so there aren't a lot of quests (horde-side at least) that I haven't done. I guess I might get back to the Sceptre of the Shifting Sands quest chain though, just to see if I can get it done before Cataclysm comes out. I think I have a fair way to go with it though. And if I can muster up the patience, maybe I'll farm up a few old world leatherworking patterns I'm missing before Azshara gets changed forever.
I recently rolled a Nelf (fellow horde, please don't hurt me) to play with my girlfriend, so maybe I'll run through a few of those Alliance friendly areas you mentioned, just to see what's what.
