good luck on your build,Pacients very first then First thing I would get would be a clymer book even before the forks, for your fork pick if the springs are sagging some new springs if your going to run the short fork seal covers the dime city cycle ones suck, go to honda its a more durable rubber,
imo, the only spray can paint would be primer you can get a 2 quarts of paint hardener an clea coat for approx 80.00 an get a small detail gun from harbor frieght for 12.00 you can make your own spray booth with 1/2pvc an shower cutrains for 30.00, for your polishing parts if they are really bad chemical stripping to get the crap off then steel wool. or go to harbor fright again an get the small air toold an hook up a polishing wheel, some of the parts on the bikes can be polished on a bench grinder with a wire wheel handle bars make your own if your going with a straight drag bar 3 bucks for some scrap 7/8 at a metal shop. carbs id get rebuilds, an for cleaning them boil them boil in simple green with some degreaser, you can do it with your pistons also getsem super clean. top end rebuild kit vesrah if your pulling your valves bench grinder with wire wheels takes the 30yr old carbon right off, if any of your piston rings are broke serviehonda.com cheapest ive found them so far 29.95 a set, if your tank is rusty inside chemical dip nickle plate to seal heard the tank sealer over time breaks down. enough rambling from me.. good luck on the build.
