I don't use names in any of my playing macros. The only time I use names is for /invite and setting /focus. I use options for all my heals and attacks. I focus my main char. When I need to heal, I use /cast [target=focus-target-target] SuperAmazingHeal. It looks at my main, then its target (which is the mob) and then its target (which would be the person tanking or attempting to tank). It makes it simple, since if anyone steals aggro and is getting beat on, the heal still works. I will say I put in a /cast [help] SuperSimpleHeal on my shammies since I wanted to help heal for BG's.
