These are interference engines. So you really need to keep an eye on that timing belt.

As per cooling system: are there any components shared with the Camry diesel (like thermostat, water pump, etc.), or are they specific to the van?

I'm not sure to be honest. It's very likely they are the same. The only thing I've found different so far is the oil filter thread.

One resource I use often in the BMW world is a parts database correlated to the vehicle VIN number. Does any such resource exist for older Toyotas?

I don't know of any VIN based database for these vans, but you'll find a lot more information here
