You can do a custom layout that may have all of your guys together and the rest of the raid group where ever. I drive my healer and can use my clique + WOW raid UI + Jamba to heal my crew or the full group in BGs. And I also have the typical spam cast sequence for healing tank in an instance but my lvl 85 crew has not been successful in 85 cata instances... think it is a CC issue more than a heal issue.
