I am still using a macro only set up for my heals, i haven't set up a grid/vudo/clique yet because i have been too lazy i guess.

I have a button on my mouse for each team member that targets them and heals with different spells depending on what modifiers I use.

The first macro is an example of my target macro (on my priest) and the second macro is the macro i put in the ActionButton12 location (the = key by default)
Code:
/target #TankName#
/click ActionButton12


(ActionButton12)
/Stopmacro [channeling]
/use [mod:Ctrl, mod:Shift] Greater Heal; [mod:Shift] Heal; [mod:Ctrl] Flash Heal; [mod:Alt] Power Word: Shield; Renew
I don't know if this will help you out or not, but maybe it will give an example of one way to manage your healing.
