Pre raiding gearFollow

Hi everyone

i havent really been able to find like a "guide" to what sort of gear you should have pre raiding. i have only just dinged 70 yesterday and would really like a guide to tell me what options of gear i have for each slot and where this equip is obtainable from if anyone has a guide like this or knows where one is please let me know.
any other suggestions on equip related help you can give me that would be very much appreciated
I am an affliction Lock if it helps
Cheers
