You really don't have too many options. Each panel manufacturer uses different breakers (their own) which are not interchangeable. Breakers also must be sized so as to not allow too much current to a specific wire gage. I'd stay away from GFI (ground fault interrupter) type breakers with their extra sensing circuitry.
The National Electric Code sets the standards regarding electric panels and breakers. Any licensed electrical contractor can inform you better of the permissible options.
