chardev 8 - Cataclysm Beta
As for gems, it's perfectly customizable depending on spec - although personal experience tells me that staying at or above 8k unbuffed is a wise choice.
The T2.5 chest is used instead of the outland gem chest, as it looks ridiculously ugly - we all know looks matter, and in order to get the spell pen.
Spell pen is probably a little bit more valuable as an affli lock, but I would try to stay at or just below 60 spell pen, as it's fairly useful regardless of spec.
Although I didn't add any talents, the gear is probably close to, if not entirely BiS for all specs.
