Before I swap to the discs / will I need to change anything else to make it work well # proportioning valve # master cylinder # with out tomuch slop at the pedal /86-4-4 standard trans gl wagon Thanks Ned.

With the EA82's such as yours they already have a proportioning valve so you should be fine. It's as straight of a bolt-on upgrade as you can get. Master cylinders are all the same. Just bolt them on, bleed them, and go.
