I'm still waiting for my board but if you want to connect the servos they plug into the flyleads that you can see here:

The leads are at the far end. Two are sockets for the elevator and rudder channels and three of the leads are plugs to go direct to your radio receiver. The "extra" plug was connected to the throttle channel in the prototype airplane.
There is a free, student edition, C compiler available at microchip.com (exact site depends on your location) which will work with the MPLAB IDE from the same people.
I presume that you know that you link your C code with the IDE's assembler; and use an ICD 2 to load the code into the board's processor.
My ICD 2 is on it's way from:
