You are talking about some serious work there that will cost you thousands....any chance you can get another car to start with? You will save major time, money and headaches if you can find a second car then use all the good parts you have.

Rust repair is very time consuming and not an easy task for someone without experience. I'm not saying don't try but if your looking for an easier more cost effective way to deal with your issues then you may consider that opinion.
