Bear tank + 4 shams is pretty straightforward.

Setup bear tanking button-masher macro on same key as shammy DPS button-masher macro.
Setup hotkeys for targeted and AoE heals for the shams (no set up healy keys on bear; shifting out of bear to heal by accident when targeted by heroic boss = bad).

Then, just faceroll like normal. If you're looking for the specifics of the bear tanking macros, we've posted those in other threads.
