Resto Druid & Mage Builds for PVE

I am about to level my second team from 70-80. I have a pally tank, 3 mages, and 1 druid. The druid will be the healer and I need to figure out some good healing macros for him. My mages are currently speced deep arcane because I loved the run and gun dps and 2min invis. I guess arcane blows for PVE compared to Frostfire Bolt spec. The new patch should help arcane a bit I guess. My druid is currently in t5 Tanking gear. I would love for him to tank and pally heal but I think over time it would be easier to have the pally tank and druid heal. My druid has not been resto since I use to raid AQ and Naxx. The below specs are what I am considering for both. I dont know if the druid should be in tree form or what. I have not healed with him since pre bc and I didnt have a tree form :).

Anyone have advice on builds for these guys?
