Thanks for all of the suggestions. I took an hour or so to start taking things apart and generally like what I see. Looks like there's ample grease in most of the places I looked for it. Brake pads are hard as a rock. They've gotta go. The brake cables seem to rub rough on the inside of the housings. I pulled those and will be replacing them maybe later tonight. The bike was apparently stored on flat tires. There are some nasty-looking cracks on the sidewalls in the spots where they supported the bike's weight without air in them. The rubber all around has a chalky appearance. My suspicion is that this is ozone damage. I pulled the tires and it looks like the cracks are superficial. I cannot detect any irregularities from the inside of the tire. I'm haven't yet decided whether I've got to replace them right away. I probably will before I put any real miles on the bike. Sometimes I have to remind myself that I'm the "breadwinner" and that being injured can come with significant cost.
