Stuff to know about prot pally AoE:
You want nice shield spike on your shield. (Thorium or Fel Steel)
A shield with damage reflect/on hit of some kind is nice ( http://www.wowhead.com/?item=25828 )
Try to get gear with block rating
Redoubt
Use Blessing of Sanctuary
Holy Shield
Retribution Aura
...
So, with this, thorns and a healer, you can practially pull all the melee mobs you like.
I'd spec the druid for Brambles (increased damage from thorns) and then rest in resto.
HoT the pala and cast hurricane, Rince and repeat.
Point with AoE'in with pala, PULL A LOT! not 5-6 or maybe 10, go for 20+. Just make sure Holy Shield is always active,
heal with the druid and maybe assist with Hurricane.
