Here's what I'd suggest.
1. Bore the hole in the plate well undersize to start with.
2. Make an arbor to fit the hole.
3. Turn OD on lathe with arbor mounted in the chuck (If you have soft jaws true them up first)
4. If you can hold the OD of the plate in your chuck then do so to finish bore the ID. If not then you'll have to clamp the plate on its outer edges to the rotary table, clock the OD, then machine the ID with your mill.
5. The bolt holes will be best done on the rotary table using the above set up.
Of course there are plenty of ways to do it and it really depends on the equipment you have, but that would be my approach with the information you've given us.
Great buy by the way. It looks like you did well with that.
