Need some direction with my Mom's 64 Dart

Of course, I want it mechanically sound before any driving goes on. I want the focus to be on mechanics and the body can wait. It is a slat 6 with pushbutton transmission.

I'm not too versed in all things Dart so this is a learning process for me. I could do some of this at home but I don't know if investing in all the tools needed would be worth it?
