Not sure what your long-term goals are but assume you just want to get the car into drivable condition at this moment in time. It's all about restoring the systems that have aged beyond reliable use.

Re-place the fuel tank. It's not even worth the bother of inspecting and cleaning and the replacement tanks (assuming it's an A body) are cheap. Install a new pickup and sending unit. Think ahead if you plan to install FI later. Then you will want a FI-ready tank even if you don't need it now. It's more expensive than a standard tank but cheaper than buying 2 tanks in the long run. Check your fuel lines for signs of rust. If you can easily pinch a rusty fuel line with a pair of channel locks and a light grip, install new 3/8 fuel lines and a new fuel pump also. New or used make sure to flush your fuel lines with brake cleaner and compressed air. These things are all pretty inexpensive.

You can rebuild your own carburetor (if you are capable) or get your carburetor rebuilt while you work on the car. Honestly, forget about all the high dollar performance builders for this, you're not at that point yet and will just waste money. National Carburetor Rebuilders can rebuild your Qjet for $239 plus return shipping or sell you a rebuilt and recolored replacement for $329 plus your core (non-numbers match if that's a concern). The carb rebuilders here are going to give you a million reasons why you shouldn't do this but my personal experience with 3 of these National Rebuilds has been bolt it on, fire up and drive away, They all were just fine without touching a thing. I twisted the mixture screws on the first one for highest vaccuum and it was in the in the ballpark, the others, I didn't even bother based on how well they ran. The choke preset and function was just fine right out of the box and the carburetors looked brand new.

Flush and fill the radiator and check for leaks and good circulation. Replace the belts and hoses including all radiator, heater and vacuum hoses. Replace the radiator and water pump if they are bad. Of course you will need a new battery and a voltmeter to check alternator output.

Get good tuneup parts including points, rotor, cap and wires and install. NAPA is your best source for reliable parts. Then do a brake inspect and at a minimum replace the brake hoses and replace any leaking wheel cylinders if needed. Once running and stopping reliably, you move to the finessing of what will be a finished car (if there is such a thing)
