Frankleech-you were wise to pull in the reins on the lp 'archive' project while still using low-res digital storage. Copying LPs is a lot of work, and you really only want to do it once. Saying that, unless you have a really compelling reason to do this, you could take the simple, yet completely satisfying route-just play, and enjoy, the actual vinyl as needed. With decent care, they'll last forever.
As far as a PS upgrade, any move up must be considered along with the quality of the entire system, but I'd recommend doing some research, then buying used-you'll be able to do a long term audition of as many different models as you like, with re-selling as your road to little financial stress.
