FJ40 Cooling System Upgrade Questions

[jvfj]

1977 FJ40 - 2F Engine: Need to Replace my leaky core radiator. This is primarily a brewery tour vehicle. Trying to keep the car as original as possible but would like to reliably drive on freeway occasionally without overheating.
1. I've been reading on this site about bad radiator hoses, etc. Where is the most reliable location to purchase quality cooling system parts, so I'm only doing this once.
2. Is it worth upgrading the radiator to an all aluminum unit over the OEM radiators available? I would break my "original parts" rule if it greatly improved the function of the cooling system.
3. Already planning to replace the leaking Radiator, T-stat, and all hoses. No indications of pump wearing out, but is it worth doing that as well, while I have it torn apart? Found in the past that the next weakest component seems to always fail after you replaced the already failed part.
Just looking for some recommendations/validations on what I'm planning to do.

Years back I bought a brass 4 core on close out from Radiator King at a very good price. I like brass I can and have fixed brass radiators in the field, not an aluminum guy.
I think CityRacer in the vendor list has hoses, others likely have them too. I keep my old belts, hoses, wipers ect. as back up - I change before failure. Always good to have a spare alternator, starter, water pump thermostat sort of things on hand - they don't go bad on the shelf.

A good radiator shop can either rod-out or replace a core and make the radiator like new.
