Korg Poly800/EX800 Users

Hi all,
I just picked up a Poly-800 for $100 that already seems to have the mod done - there are 
two (knobless) pots above the joystick that seem to control res & cutoff.  They're both really 
sticky and tough to turn, so I'm gonna open 'er up this weekend & use some de-oxit.

While I've got the hood open I'd like to do two things:
1) Make sure the job was done correctly, and..
2) Add the "patch values vs. knobs" switch.

Regarding point #1 above, I've checked out Olaf's photos and have a few Qs:
There are two diagrams, called schematic & MoogSlayer.  They show different wiring in each 
& different values for the RES pot (50k vs. 10k).  Which is correct?

Regarding point #2, I'm not sure what value resistors to use here, since I bought the synth 
with the mod already done, hence no VR2 & VR5 to check.  Any suggestions?

Thanks in advance for any help.
