Rogue Specs

Here's a question to all of the rogues out there.
I have a level 66 rogue, with all epic gear and enchants and when she hits 69 I want her to be absolutely remarkable at pvp.
She has duel spec of subelty and mutilate. I just purchased the 1k for mutilate spec and have grown very used to relying on stealth/ambush because of subelty.
Whenever I spec to mutilate, I have no idea how to be mutilate and what attacks to use!
If I could get a simple reply on how to rotate my attacks to absolutely own in bg, that would be great!
And how i can not rely on stealth so much when in subelty!
