Lance: The braking surface of the actuator should be very smooth as would be same for braking surface of housing. When you speak of roughness, are you suggesting corosion, rust, etc.? Or is it circular grooves caused by braking? I wouldn't worry too much on those circular grooves as discs will smoothly wear into those.

If that crack is not into the braking surface you can try welding it. You really have not a lot to loose on that. I suppose the other thing one should look at is cost of a replacment. Just maybe it is not worth welding. If welding warps it even a wee bit in the braking surface area, it will be quite useless. Those were engineered to have full surface contact when braking.

Just about any brake cleaner should clean those parts. I was quite surprised when you suggested you removed the springs with your fingers. I though, now there is one guy I wouldn't want to annoy to point of a physical conforontation. My experience has been those springs break before they become that soft. Someone must have got the brakes very hot at some point, probably what cracked housing as well as removed temper from springs. Always was one thumb rule with Farmall disc brakes, if they lock or jam on, stop and back a bit, they will release immediately. If you keep driving they never let go. When these were new most of us had graduated from machines that didn't work that well. Most younger folks never knew those machines that didn't work as well.
