Both modules are stand alone. The 8 pin socket on the transmitter is optional. I would not cut anything at the moment.

It is my understanding that the rfPIC12F675 is just a 12F675 with RF on board, plugging the modules into the PICKIT1 is just a way to program them.

I bet the software for the PICKIT1 sees the modules as is. Have you plugged either one into the PICKIT1 yet?

One the modules are programed you should be able to power them with out the programmer attached.

Maybe...
