Love your 506 panel, they are rare and beautiful to my eye! I recently acquired the correct size and type rims for my G506 and after looking at the photos of yours I'd say mine were in the same condition. As long as the pitting is not too deep and the ring and it's contact area are in good condition there is no problem with these wheels.
Although there is a garage in my area that mounts tires on Budd style wheels When it came time to mount my new tires I decided to do it myself. The hard part is breaking the old ones down which you have already done and like I did you'll be starting with bare rims and new tires which is a little physically demanding but not all that hard to do when mounting them your self. Take some simple safety precautions (you don't need a cage just chains) and study some of the excellent how to videos that are on the web and it can be a fun project, not something to dread.
In my over enthusiasm I did all six of mine in one day plus put them on the truck, if I were to do it again I'd spread it out over a few days and make it more enjoyable. There's a lot of bad stories out there about split rims but the Budd's are much better and with a little care can be mounted at home safely.

PS
I'd stick with the 7.50x20 NDT'S, the 8.25's are to tall and mess with the final drive gear ratio too much and make these trucks a lot less enjoyable to drive.
