You will need bushings for the waggy spring eye size. Then the correct size sleeves to go inside them. If memory serves u need 1/2" sleeves for the shackle ends and 9/16" sleeves for the frame ends. Personally I run poly bushings. They might not be quite as soft as the stock rubber, but they last a heck of a lot longer. Just be sure to grease them when installing.
As for paint, yeah u could just clear the surface rust and spray bomb them. Though it's better to tear them down and do each leaf individually.
you do know also that the Waggy springs, in addition to providing lift, can be used for stretch purposes as well correct? if you install them for stretch you will need to do some driveshaft modifications and lengthen your brake lines at the minimum
