I think Tim covered the other questions pretty well, so I'll only answer this one.  Earlies use 6 bolts on the ring, lates use 9.  It's possible to have a good machine shop use the three common ones for alignment and drill 6 more to install a 3.89 in a late - the ring and pinion are otherwise dimensionally the same for earlies and lates.    Be aware that the ring gear is heat treated steel, so it takes pretty good tools to put the holes in.  Aftermarket R&P sets usually have both patterns drilled by the manufacturer.
