I wouldn't recommend a shaman due to the rarity of gear for resto shamans and the lack of a talent giving mana regen while casting
First of all... hard to get
gear for resto shaman? And that list doesn't include all the leather and cloth healing gear which doesnt have spirit on it. Which game are you playing? If you had been talking about ele shaman than MAYBE I would have given you some credit.
Secondly... no mana regen?
This, and the fact that Mp5 from gear, unlike spirit, is NOT interupted while spellcasting. Seeing as shaman are Mp5 stackers, NOT spirit stackers (spirits is absolutely, 100%, worthless for shaman), almost the entirety of their mana regen will persist while casting. Facts are nice
As far as the OP goes, I would recommend rolling any healer besides a druid. Not because I have anything against druids, but because its more fun to have a couple different classes than two of the same. A shaman or priest would be more versatile in endgame healing, as a holy priest is a great raid healer, and a disc priest is a good MT healer, while a shaman is good (but not the best) at both with the same spec.
A paladin would be the best while leveling as it gives great versatility, wears plate, and does really good damage. It also allows you to switch roles if say your wife decides she doesn't want to tank anymore and wants to try healing. Then you can switch your pally to tanking.
But really you should play the class that most interests you, as that will keep you playing.
Probably would have been quicker to say Feral Druid + Innervate = No MP problems for any healer.
Anyways, any healer works fine, but I would probably not choose a druid because of the overlapping buffs and the potential conflict over drops should one of you wish to switch / dual spec into the other's talent tree. If you want fast leveling, roll a pally and go ret with her feral to gib stuff quickly as healing is rarely an issue while duo-leveling (plus ret does some decent healing for the 2 of you with its normal dps abilities)
If its only between priest and shammy, i would take shammy just cause they are rarer then priests :)
