Lots of good stuff. Here's the TL;DR so far.
If the oil pressure was good, and you're cheap like me, keep rocking the same bearings. I wouldn't even bother checking the clearance.
--- If the oil pressure wasn't great, I'd replace the bearings and check the clearance.
Replace the timing chain. Spend a little money on a name-brand. Personally, I think the stock link-type are just fine.
Check to make sure the oil pickup is set at the right height, and then put a tack weld on it or braze it.
Replace the front and rear seals. I've successfully reused the plastic timing cover with a little dab of sealer in the corners, but a new one's only $20 on RockAuto.
Replace the freeze plugs if they don't look new. Around here I'd just check them, but you're in Michigan.
Flush the coolant passages until the water comes out clear.
Check the oil pan condition.
The water pump is your call. They're easy enough to replace that I'd only do it if mine were seeping, but you are right there right now.
