My learning continues.

I successfully extracted the power steering pump, though it put up a very respectable fight.

So now I have to decide whether to open it up and try to replace the bad bits, or to just order a new one. I can't find them on JimK's site, and JimB has hopefully gone home by now, so I'll have to scour the archives for a part number.

[EDIT: my lovely wife just walked in with the mail, and what to my wondering eyes should appear but the GMCMI Parts Interchange list, and yes it includes several options for a power steering pump, including a couple from NAPA -- 81-6734 and 81-7434. So I guess I'll start there. Thanks Billy!]

Other thoughts and learnings:

It would be really smart to cut a rigid board that covers about 2/3 of the inside engine opening.

Some day, I will arrange my life in such a way that I can have a service pit off my driveway.

The downloadable X7425 Maintenance Manual is missing some very important pages regarding the power steering system. Tom Lins' DVD version of X7425 has all the pages.

The power steering fluid that came out of the pump smelled positively awful. The new stuff doesn't smell like roses or anything, but the old stuff was nauseating. I think it got hot. I don't know whether this suggests a particular sort of pump failure.

Fluid manufacturers should really put the flash point of their product on the packaging. It's probably around 400 degrees, but it seems like useful enough information to put on the tin.
