To answer a question about healing your team in a 40 man. Use Jamba to mouseover heal your team so its easy to find your team.
I replaced all my heal Hotkeys to mouse over macros:
"/cast [target=mouseover] Renew"
And disable self casting in the wow options so you can spam buttons without self healing if you don't need to heal your team.
Since I use /focus target and Interact with Target, I can keep my target one the player I want to kill, but just mouseover my team in Jamba to heal my guys.
You guys probably use something more fancy than me.
I'm using hotkeynet with 2 PCs.
