Just a minor correction: The Victors translate the RC style PWM signal (~1ms-2ms pulse) into a straight duty cycle (0-100%) and direction signal for controlling the actual FETs in their H-Bridge. The Spikes are configured similarly to an H-Bridge, but use relays instead of FETs. Relays are electromechanical switches. Notice the audible click when they are actuated.
The MPLab IDE is fairly easy to set up and use from my experience. The code FIRST gives you takes a lot of the learning curve of programming micro-controllers out of the picture and allows you to code basic functionality without knowing the particulars of the device. It may seem intimidating at first because of the sheer volume of code, but once you figure out which sections you need to be concerned with you should find programming the robot controller straightforward.
