Unholy pvp friendly specFollow

Alright, so I'm not asking the question of whether to go frost, blood, or unholy, I know I want to go unholy. Not only is being a necromancer in plate appealing, but the fact that I can have a permanent ghoul pet (like a hunter) and the fact that I can explode corpses leaving bloody messes is all the persuasion I need to like this spec.

My question is, what talents should I put points in to Unholy so that I can pvp effectively. Im' experimenting on my own, but I have a history of choosing talents without thinking about them so it may help to have some input.
