I always set my arrow keys on my keyboard to pass only to my followers. If I want to break follow or move/face my team without following my tank, I simply use an arrow key. Bind a key and use it for both nukes on your dps casters and heals for your healer. That way, when you are nuking, you are healing. The thing to watch out for is healer aggro. Build is important here as well as mixing in "fade" if you are playing priest. I use TwoBoxToolKit so that my healer can whisper the tank when he is low on mana. I have mana pots in a toolbar with a key assigned that is not bound anywhere else for my priest.... I might change this and use a button on the ClickBoxer interface so that I can free up that key.

You have lots of options. Part of the fun is figuring out what works for you and downing that BossMob.
