I am at the same point as you are. I bought a truck from California with very little signs of rust, it did have noticeable rust though in the kick panel area. The kick panel area is kind of 3ply. The floor pan/inner rocker, kick panel ,door pillar all pinch together here. So you may also have hidden surprises. One thing I would suggest , if adding bracing, do it so that you can mount and adjust doors properly. You will need to mount and adjust doors , checking gaps before final welding. Also rebuild your hinges first.
Collect all your parts, supplies and tools first, Do a bit of research and have fun.
If it gets a bit frustrating , take a break and Consult the forum. Lots of great members here willing to help.
