I can answer two of your questions...

the CV1 and CV2 inputs on the pcb are for the processor section.
Those jacks connect directly to the PCB w/out going through a pot.

The processor pots both connect to "pcw" and "pccw" The middle of
processor pot 1 connects to "pw1", and middle pin of processor pot two
to "pw2"

If you were wiring up a pot for FM or something, then you would wire
the right to ground, left to the jack and middle to the PCB

For both tune pots you connect the left ends to the positive and right
ends to negative supplies (when looking at the back of the pot w/ pins
down). The middle of the main tune pot goes to "tune" on the pcb.
The middle of the fine tune pot goes to "cvsn" on the PCB, but you
have to put it through a high value resistor. 4 to 10m.

You should try reading through the CGS VCO page. That info is listed
there. The VCO was one of the first modules I built, and I had to
read that page about 10 times before I got it.... but it finally sunk
in.

Its definitely worth the effort! All of the CGS modules are great.
