The ground strap is not hard to replace it is riveted in and has to be drilled out ad hollow riveted back in. Napa had them at one time or just make one. But first see if the bushings have any side play at all and turn the shaft and see if the cam wobbles at all to check it before even going to change the strap. Like Matt said the curve is what it is all about. store rebuilds cover a span of years with a middle of the road curve so it can be good or bad. Same with the one wire chineese they usually are all in fast. Really your call and your wallet what you decide to do. Points will last a long time as long as they are good quality and have a good condenser which seems hard to find in the stores now. Also make sure you get the right points for the distributor also. Verify them before ordering.
