I can only offer input on some of the questions.
The following pages from the 1960 Accessories Installation Manual show where the cables go:

The bed wood planks are different sizes, hopefully another member will provide sizing. I have an aluminum diamond plate floor so can’t help there.
It sounds like the choke knob is stripped, which might be because the cable itself is so old and crusty it requires too much force to slide through the spring jacket. The knob can easily be reattached with JB Weld or JB Kwik epoxy. It’s available just about anywhere including Walmart. Before reattaching the knob however, I’d check to see if the cable is easy to pull by operating it with a pair of pliers. Hold the gas pedal down to free the carb linkage, and cycle the cable. It should glide in and out easily. If it doesn’t, you have two options. Buy a replacement cable with the correct knob, or buy a cheap generic cable at the local parts store and replace the new knob with yours by attaching it with JB epoxy. That’s how I’ve attached my dash knobs and never had a failure. Good luck.
