Well, I bought a MTB. It'll be a while before it's ready. It's the first entirely off-the-shelf bike I've bought for myself since the early 90's or something. And the first bike I've acquired with Shimano components in about the same timeframe. A Giant XTC. I found a bar that should work for my wrists and shoulders.

It's only got 3.5 degrees of sweep. So about half of standard.
I also found some shoes that don't fit too bad, considering my misshapen feet (I busted up the right one pretty bad and it didn't heal straight). Giro shoes seem pretty good. I don't think I'd want to wear them for a 5 or 6 hour road ride, but they should be ok for shortish MTB rides.
Anyway, while installing the cleats last night, a screwhead broke off. Is this a sign? Or just bad luck? Thankfully I had another screw with the right thread size and pitch, though it was about an inch too long. Cut it down with the dremel and ground it smooth on the grinder. Then took off the burrs on a belt sander. Fit perfectly. Glad I have a garage full of power tools!
I'll report back after I get some time on the bike. Strangely, I'm looking forward to the change of pace and scenery. It may end up being a bit cooler on the trails during the summer than on the road.
