There is also a moonwell at Ruann Weald in Blade's Edge, and if you feel like porting from Shattrath, there's a Moonwell in all of the main cities, too.  For alliance, there's a moonwell in the Park in SW (though it doesn't look like one), in the building in Darnassus where all the priest trainers are, and there's also one somewhere in IF (Mystic Quarter, I believe).
