To interface the banebots planatery to a FP motor you just press on the appropriate pinion (sold by banebots) and bolt the motor into the gearbox.

For the FP motor, I'd stick to the 42mm gearboxes and stick the 108:1 ratio or less. According to Joe Johnson's calculations and my personal experience, a ratio of 140ish:1 or more is asking for trouble. Some teams have had no problems with the 256:1s, but I'd play it safe and use the lower reductions.
