I have no Idea where to start

Start with all the safety stuff. Ball joints,control arm bushings, new brakes, make sure all your steering equipment is good if not replace it. Once all the safety stuff is taken care of and you can safely drive it......get rid of those damn wheels. Hahaha those things are god awful. Lol but seriously once its driving (safely and dependably) start on rust repair body work new paint etc. Then when that is done start upgrading the performance aspect. Its alot easier to stay motivated and inspired on a project you can jump in and drive after a long day of hard work. Imo
