Elixir of Major Agility
Haste Potion
Ravager Dog/Warp Burger (if you can't figure out which is right for your spec, LOL GL WITH GEAR)
Flask of Relentless Assault (if you feel like going for the flask, which is sometimes cheaper than pots)
EDIT
Oh, and Health Pots. They're on the same cooldown as Haste Pots, but some fights they're incredibly nice to have.
