I always have the AC on even during the winter to dehumidify.
I'm pretty sure G man your 550 has plenty of HP to spare and we're not really concerned about wasting gas driving blown V8s.
I do turn the whole system off if I'm seriously racing/testing out my car.

None
I would assume that the system is smart enough not to engage the a/c unless it's needed, so I don't think extra consumption would be an issue.
I suspect the on/off button is just enabling its activation if needed.
