As far as the power supply goes, to get the board spec'd voltage (above 7 volts if i recall correctly) you can connect it to one of two places: the red wire of one of the PWM outputs (assuming you have a charged backup battery--this battery is directly connected to the power pin on every PWM output) or the 12 v system on the robot--this will require you to run a wire from the circuit breaker to the power pin on your IR board. If you use the RC's PWM output, ground goes to ground on the controller. IF you use the 12v system, ground will have to go to the ground on the breaker panel (correct me if I'm wrong).
It has been rumored that the board will function with only 5 volts as input, meaning you can connect the power pin to a digital i/o's power pins, but this is not advisable as the spec sheet says that the board needs above 7 volts, and there is a noticable drop in performance with the drop in voltage.

Each one of the signal pins coming from the IR board will need to go to a separate Digital I/O pin on the RC, and at least one ground needs to be connected between the IR board's ground and the RC (I could be wrong here, but it will not damage anything if connected in this fashion).
