3 Setups have been "proven" to work in PvE content up to Heroics and Kara.

5 Shaman (massive dps without being squishy)
1 Pally / 4 Shaman (massive dps /w tank)
1 Warrior, 1 Priest, 3 Mages (lots of CC)

There are other groups that I'm sure will work, but these are "tried and true" right now.
You can add Prot Pally/Holy Priest/Balance Druid/Fire Mage/Elemental Shaman to the list.

Pretty much anything involving a tank, healer, and 3 ranged DPS will work. I prefer multiclass groups, just to be able to play with the synergy.
