dirty solution to the spam thing, not quite sure how to pass the target to alts though. Gimme a bit more time I'm sure something will come to mind.

DPS pseudo-macro
Code:
/click [target=mouseover,help] healmacrobutton
/cast dps of doom spell
heal pseudo-macro on that button you told it to click in the DPS macro
Code:
/stopcasting
/cast heal of infinite help spell
