Feeling in over my head and not sure what to do next

Where in the DFW area are you located?

What I can see from the pictures is a major fire hazard. You need to get the correct hard line from fuel pump to carburetor inlet,

and install a fuel filter in the carb inlet like it is supposed to have.

Most importantly, You need to find someone who actually knows how to correctly rebuild a Quadrajet.

Your other option is to replace it with a new carburetor like a Holley or Edlebrock 1406 with electric choke. If you go this route, You will also need an adapter to run a square bore carburetor on your Quadrjet spread bore manifold.

Yes, you have the right idea; the ones I use are just general purpose "nested" dual springs. (photo attached) Sometimes the kit comes with a mounting bracket that you can put under a convenient bolt that is in about the right spot to give you reasonable tension on the spring at full throttle; and enough to keep the throttle butterfly closed at idle.

If there is too much tension on the spring I would worry about the throttle bushing getting worn so there is a happy medium somewhere that you will know when you feel it.

I have seen these same springs described as Holley springs and Quadrajet springs.. you can google "carburetor dual springs" and see what you get but the type in the photo are usually hanging on a peg in the auto parts aisles.

Oops I just noticed Grumpy was way ahead of me in mentioning the high arc in your fuel supply line.. sorry Grumpy, I didn't see it before I posted.

One other observation I notice your spark plug wires are touching ground or metal in many places and sometimes moving parts. - That may or may not cause an issue - but I would keep that one that looks to be touching your temp gauge wire at least 1/4 inch from the wire.. (maybe I'm paranoid)..
