Here below follows stats for each class and spec and what you should aim for before setting foot inside a raidinstance. Note that you don't need to fill all the demands since they are not fully calculated on pre-raid gear, but this is what you should aim for!
Healing classes:
Paladins
~650 int
~1450-1500 Healing
~24.00% Crit
~100 mp5/casting
Druids
~650 int
~700spirit
~1250-1400 Healing
~200 mp5/casting
Shaman
~650 int
~1450-1500 Healing
~200-250 mp5/casting
Priest
~700 int
~1450-1500 Healing
~200-250 mp5/casting
(Not very good with priest, so once again please tell me if I'm wrong in anyway!)
Note: After looking through several chars on the armory, the mp5 seems like quite alot, so please correct me if I'm wrong on that one
