As for retrieving the code in general, you're probably better off just rewriting it, and using the experience two ways. One, teach new programmers how it all works (because it is quite a bit different from writing a generic win32 program), and two, figure out how to use some sort of more robust storage solution, be it backing up your code in several places or something like CVS.

I started to think about this and got excited. Then realized it is not possible to access the necessary 4 pins from the outside. You can only access 3 out of 4 of them from the outside
SO CLOSE!!!
Just for the info the 3 are as follow:
GND- any ground anywhere on the RC will do
PGC(program clock)(RB6)- Digital I/O 5
PGD(Program data)(RB7)-Digital I/O 6
MCLR(master clear/reset)-
No hope of accesing this from the outside
