Re: Attendance at gigs?
We usually post myspace bulletins before most shows, sometimes blog it, and occasionally (for special shows) send out event invitations (which is a pain but it is personalized).
If you have some close friends who regularly attend your shows, you might look into doing gig swaps with bands in neighboring cities - that way you can bring your guys with for your shows, and play in front of a new audience and they bring some when they come to your city.
Also look into playing new bars/venues in your city which have a regular crowd show up on a certain night (say every Saturday night).
