I should add, not included in most FF schematics are the LED and current-limiting resistor (CLR) for the LED.  Obviously the LED is going to mount poking through the top of the enclosure somewhere.  But it can be convenient to mount the CLR on the board, it just comes off the "-9V in."  (Negative assuming PNP)

There are several ways to wire the footswitch.  If you ground the input in bypass, you won't need a pulldown resistor at the input to avoid switch popping.  Not needed at the output, since the volume pot acts as a pulldown anyway.

You can imagine a grounding bus, that connects to both jack sleeves, and Lug 1 of both pots.  Then your board grounds would connect to that bus at any of those points.  For the FF, that's Q1's emitter, and one end of the 25uF cap on the fuzz control.  You can also mount that 25uF cap on the fuzz pot itself, and save a little space on your board.

Thanks for the advice, those are all great examples of things I had no idea about!
