Help! I bit off more than I can chew! Body work

understood no disrepect taken any and all help or advise much apreciated. not goin for show room or even close at this poiint. no harmful chems been used with my son around about all hes interested in is watching. gonna get it as good as i can till i can get it painted and the painter can do the finish work on the body. my biggest goal now is to stop the rust and keep it somewhat prsentable as i drive it regulary. the top was bubbling and peeling and the guy that i talked to about paint didnt want to do the removal of it so i figured id give it a go while saving for the paint.
