Milt,
Welcome to the engine board. You'll be a great addition. I think you have a good plan. If you upgrade the pump you'll need the oil bypass mod on the case and new pressure relief springs/pistons. (you probably already know this, but just in case you don't). The rebuild kits can be a good deal. You need to shop around to get the one with just what you need. Some of the kits come with rings and you may not need them if the set of pistons/cylinders are good already.
Most of the time a mag case engine needs lots of machine work but for your purposes you probably don't need much except cleaning. The early engines with the biral cylinders were much easier on cases than the later 2.7 engines. I highly recommend reading the engine sections of Bruce Andersons 911 performance handbook and Waynes engine rebuild book. With these resources and our help you'll have no problems.
I've rebuilt engines with old rings and valve guides when they were within wear limits and they work fine. Obviously you won't get as long a life out of a motor with old parts though. You can plan to spend around 2000 dollars even without doing much machine work because parts and tools are so expensive.
