Head on off to Coerthas Highlands. Many people, I've seen, stay there till 50. Svara gives you around 20k alone not to mention the two events leading up to her which give 8k exp each.
Personally, I'd stay there till 42 then go to Mor Dhona afterwards. It's more compact and Chimera spawns there. Highlands are so swamped that you can barely see Svara from even a moderate distance at peak times. :X
