Nice! Yeah, I have mana problems on Prince, too. But I have Mana Tide Totem on my resto shaman, so that really helps out a lot. The rest of the fight I just chug mana pots as often as I can.

Two of the guys that were in the group with me are guildies, so I have macros already in place to heal them that I'm used to using when I bring them in with me in heroic runs. The other PUGs in my group I assign to my Z, X, and F keys once they join the group. I hard-code their toon's name in my Z X F macros to make it easier for me to heal them. My DPS is always [target=focustarget], and my main heals are [target=focustargettarget]. I drive with my pally, so I use more [target=mouseover] and shift+mouse buttons on him so my dps do not lose their targets.
