Hi, I need to make a remote capable of transmitting many different commands (+/-12), and controlling the speed of two DC motors, like in an rc car. I want to use PICs as the center for controlling the remote.
I have quite a few different types in the 16F range, but I am only really knowledgeable with the 628.
I am aware that there was two similar threads recently, one by RoboticInfo...
Please recommend what RF module should I get, or what should I do?

I would suggest you get modules with in-built Manchester encoders and decoders, this allows you to use simple RS232 type serial data transmission. They cost a bit more, but it's worth it as it simplifies the project so much - and PIC Manchester routines seem pretty thin on the ground!.
If you want to use PIC's to do it, choose one that has two PWM channels for the receiver (like the 16F876), one of my tutorials shows how to provide PWM and reversing for two motors with this.
There are various manufacturers of these modules, have a look at this one for an example. These are transceivers (two way), and include Manchester coding - everything you need to know should be on this site?.
