Opinions on life expectancy and brands for Toyota Cressida fuel pump & wheel bearings?

To replace the bearings, am I gong to need any tools that I can't get at Autozone, Advance, etc.?

Where do you live, do you live where roads are salted, is car rusted. I would not worry about those items, front bearings maybe when brakes are done. If car has rust and pump is in tank it will cost alot more as my tank straps and lines rusted through. What you should worry about, is my 91 had its brake and fuel lines rust completely through years ago, I lost brakes, had a minor accident and drove home on the emergency brake that didnt work well. Hoses, tires, belts, brake, fuel lines, radiator, thermostat, wires, and the list goes on with things you might really need.

The original pump was probably made by Denso, with Toyota's name on it.

Denso and Aisin are Toyota OEM suppliers. I am not familiar with "Asian" but if it is Aisin, the quality should be good.

I would not bother changing the fuel filter unless you think there is a problem and it has tested bad. The Cressida is not known for going through fuel filters or wheel bearings.

A more common problem with Cressidas is leaking cam tower and head gaskets. I would pay attention to those areas first.
