Gigging thing - opinions, please!

(With apologies to diffrentcolours for poaching the title...)

There's been a fair bit of debate about gigs and promoters elsewhere on LJ today - mostly about a specific incident, but with some discussion of what should be expected/provided, good practice and all that sort of thing.

And thinking about it, there are a few musical and promotery types reading this journal. So...

What advice should be in a FAQ/guide for first time gig promoters?

Or, from the other point of view, for new bands who are about to start playing gigs?
Edit: actually, there seems to be a very decent take on the band's checklist here. Which the gigging thing lyrics indirectly reminded me of... :)
