I am alittle lost here.

I know some people make a cast sequence dps key with chain heal at a couple different spots in each shamans rotation so that with healing stream totems and spamming that dps macro you never really have to do much in the way of heals

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.
