A tip:

When you get hurricane and other spells which needs channeling, put a [nochanneling] into your wrath/starfire dps macro so you can keep spamming the dps button whlie the other toons are channeling an AOE spell.
I have this in most of my macros.

Also, for healing, I suggest Vuhdo combined with ISboxer and repeater regions. Works like a charm.
Eventually you "will" need a program which can broadcast mouseclicks like mentioned in the second post.
