Looks like you are assembling a nice list of things to do so you can get it running, drive it, and assess whether you want to go to more involved projects like replacing all bushings, springs, shocks, ball joints, tie rod ends, dealing with oil / fluid leaks, interior, seals, etc, etc. Get it running but keep in mind that it will handle far better once you go through the suspension and replace everything that has worn or deteriorated in the past 53 years.
My advice would be to resist the temptation to take the car apart beyond weekend or maybe 1 week projects. It is super easy to turn this into a 3+ year process before you even know whether you want to keep it or not.
Also, if you have the tank cleaned and the inside coated by a radiator shop...they often will use a product called Red-Kote. I had mine cleaned at a radiator shop but did the Red-Kote myself. I have had no issues with the Red-Kote product. But, I think it is important that you let Red-Kote cure for a month or more before exposing it to gasoline.
Congratulations on retirement. I retired 2 years ago and have enjoyed every minute.
Take care and let us know how you are progressing.
