Nice. I spend way too much time looking up hole diameters. Especially the inch fractions to millimeters part.
What "bench" reference information would be useful to you?

Yes, the pin layout and also A=Log B=Lin.......... or is it the other way around??

Lug 1 is always where the snap off mounting tab is.
A is logarithmic
B is linear
C is anti/reverse logarithmic
W is W

Common voltage for 90% of the pedals on this site using dual opamps:
pin 4 is ground = 0V
pin 8 is Vcc = 9V
All other pins should be close to Vref = 1/2 Vcc = 4.5V
If there is a charge pump on the board then the voltages will be different from what is stated above.
LFOs cannot be measured with a DMM, you need a scope for that.

IC projects. I often find myself with extra ICs and always have trouble tracking down uses for them. The hell am I gonna use these LM311 chips for??

You can make a "ghetto opamp" with a comparator. Not sure how it would sound in a pedal. I've got some NOS LM567's, find a pedal use for them!

Is the long leg or the short leg positive?

LEDs: long leg is anode (positive)
Electrolytic caps: long leg is positive. Also, polarity is printed on the body of the part.

A nice picture of outside, so I remember what it looks like. Lol
