Are these typically equity relationships, and if so, how much?

While you have good links on how it can work when they are, they don't need to be. Good people are generally nice and want to help. The tech community can be very tight like that, in a good way. A lot of people will give you their time for the asking, with nothing in return except the satisfaction of paying it forward and helping to nurture a promising startup.
