Umm Vss is the negative supply isn't it.

The programmer needs to connect to Vdd Vss, PGC , PGD and Vpp/MCLR. The 
pinout should be documented in your programmers manual.

Vpp/Mclr should be pulled to 5V (with a reset switch to ground if 
desired) with a 20k or so resistor so the programmer can take control of it.

It also improves reliability of the intial programming operation if you 
pull PGM low.
