Warlock talent help

[Eagles]

Hello first off I would like to say I am new to the vanilla warlock class. Anyways I had some questions about the talent system. Firstly how many points do you have to spend when you are level 60. Secondly can you guys explain how all three trees/specs(aff,demo,destro) do in questing,raiding, and pvp. I was thinking of focusing on demo but then I saw destro has some spells pet talents and it just seems like a power house. Anyways those are my few questions. Thanks to anyone who helps.
