[PBitt]

We use:

Holy Pally (tank heals)
Resto Shaman (tank/raid)
Resto Druid (raid heals, dots on tank)

As long as you have one solid main tank healer (holy pal or disc priest) and a solid raid healer (resto druid for example) than your main bases are covered. There are optimal setups of course, but the third healer really doesn't have to be anything in particular, but I guess I would not suggest 2 main tank healer oriented healers, as there is an awful lot of raid damage for one healer to keep track of.
