Thanks for all the condolences.

Everything is pretty much back to normal and the data files lost can all be re-entered. It will take some time, but it might be better to have the thing cleaned up, anyway.
It's a 3 year old Sony VAIO and the "System Restore" CD's worked great to get things going again. I think backup would have been more of a nuisance than this turned out to be. I had always backed up the data files on my work computers and what a time consuming process that was.
Anyway, I'm baaaack.
