What stats necessary for Kara for an affliction 'lock?Follow

Hello there!

I was wondering if someone could give me a quick rundown of what stats are considered necessary for Kara? Our guild is slowly but surely getting ourselves keyed, and I want to know: How much spell dmg should I have? What should my stamina be at? Things like that are very helpful, as well as any other tips!

For instance, is it necessary to have the Oblivion Raiment (am just starting to work on farming those pieces now, when I can) for Kara? I am not a tailor nor do I intend to pick up tailoring (Herb/Alc, and our guild is low on alchemists), so no FSW set for me =) I am also just starting to run Heroics.

Note: I play on an RP server and am an active/heavy roleplayer. I do enjoy instancing immensely and I know I would like raiding so long as it's casual, but my gear progression tends to be slow as I am RP first, PvE second. That said, I like to do PvE as well as I possibly can. Try not to laugh too much at my gear. ;)
