I personally like the nickels age as is. If you gotta do something, go refurbish. Stay light with your scrubbing. Yes to 0000 steel wool, no to hard wire brush. Soaking parts in CLR before steel wool makes it easier. Be nice to what nickel is left. Scratch marks look funny.
I like that you wanna keep the original rims. If you have any questions, PM me.
Is this refurbish to display, or to ride? You could always do a separate wheelset for riding.
Good luck and take your time.
