Good project, best of luck. The cross slide screw really should be replaced along with the mating nut. I don't know if it's the photo, but the thread crests appear close to "pointy" in the middle, while very thick and original at either end. With that condition it's impossible to get backlash minimized in the center of the travel without it being super tight at the ends.
