There are only two potential gotchas in this deal, otherwise everything is straight forward mechanical work. 1st, release tension off the torsion bars. Do this and they are safer and easier to work with than coil springs. 2nd, upper ball joints require a special socket. If you don't want to borrow or rent this socket, than any machine shop can screw in the replacement ball joints for you. I trust you have machine shops near by enough to support your engine work. They can also hot tank parts to clean them and press bushings into your control arms.
