I believe there's another thread about your drive train... look there.

As for pneumatics, you'll want to hook them up to solenoids, and then power the solenoids off of spikes (relays). Then, use the relayX_fwd and relayX_rev (X = 1 to 8) to control the various relays. Likewise, use the pX_sw_BLAH (X = 1 to 8 again, BLAH is the name of the specific switch/button - see ifi_aliases.h).
