Alright start with the joystick(commanding unit) you have.Open it and look at the circuit.you press some buttons to say the car "go left" or "go forward" etc. look at the circuit and the buttons what is changed when you press button observe it.Then take an ossiloscope and connect it to the antenna and observe if it is ASK or anything else.
About parallel port you can find lots of information on the web.But as preliminary buy a parallel port connector and some ribbon wires(ide wires in computers) and solder them to the connectors available pins.
then find a software written in the language that you want (it is very simple. www.programmersheaven.com has many)
and parallel port pins are important which pin will be connected to the commanding unit's button you will decide.Look at the parallel port pin descriptions from the web.
Good luck!
ps.my girlfriend is doing a project involving exactly same thing.she will direct a car to the patterns.using a camera above the pc and observing an area of patterns and tell the car to go to the selected pattern.

I can offer you a keyboard with all of the keys functional. Then perhaps you can write a coherent problem statement.
