You might consider a posting in "Machine Reconditioning, Scraping and Inspection" since your request covers pretty much all of that. I have to warn you that sometimes you're opening a #10 tin of worms when you start looking at refitting a lathe and most of the time not all of thr worms can be stuffed back in. Refitting the cross slide to the saddle might make some saddle to bed adjustments necessary as well as compound to cross slide fixes (the former more than the latter). If there's sufficient wear a completely new gib might have to be made. Finally you'll want to figure out why there's so much wear and correct for that.
Many folks look at the cost (including shipping the lathe, or most of it anyway) and conclude that they need to learn how to do it themselves. I don't think it's cheaper in the end but you do end up with a bunch of tools after it's all said and done.
