I settled on Bloodmoon pvp wise because it seemed to have the lowest queues. Dominion of course.

Oh I also suggest, Dominion side of course, to go to Crimson Isles for your starter zone. When you get passed the emperor choose the bays to the right of the lady giving you your new weapon, not the left. Crimson Isle leads to Deradune which is the best zone in the game, in my opinion.
