I'm 7/8 normal at the moment and currently have reforged off all my spirit and am still coping fine (last fight may test me). It comes down to making sure you are using your efficient heals. Lifebloom up all the time, rejuv on the tank all the time, swiftmend on CD, regrowth or HT only on OOC proc. If you do that then you generally are fairly mana neutral, so you can spend the rest on rejuvs and the odd regrowth or HT if things go bad. This expansion it hasn't really been a resto druids job to save people in emergencies - we seem to be the baseload healing that keeps things mostly under control while the other healers do the emergency stuff.
For my reforging, I get rid of all my spirit, hit 2005 haste then put the rest into mastery.
