Unfortunately, the best deal I found was 6 gallons for $95.64 + $50 shipping.
I can probably use much less of the probond as it is stronger and more suited for the poly-to-wood application. The problem with PVA is it is only meant for porous materials (not polystyrene), but many people working with polystyrene say it works.
What should I do? I have no idea how much glue each of my panels will require, but I bet its a lot. They are 4'x ~3.5' x 1' with 1" wells.

Polyurethane glue is WAY overkill for what you are doing. Plus, the foaming action can really be a pain to deal with.
You should just get a small bottle of Titebond woodworkers glue and test it on a pc of the foam. Titebond is just a stronger formulation of the standard aliphatic resin glue, like Elmer's, that has been around forever. It doesn't have any solvents and that's what would cause problems with your styrofoam..
Once you determine that the Tite bond isn't causing any harm, then you can pick up a gallon at a woodworker's store.
While you are there, you can also pick up a handy roller bottle that you fill with glue and allows you to easily spread the glue around.. See here:

They might also have some advice for you about materials and methods for the wood. Do you have a table saw? I'm thinking thin luan plywood for the dividers and faces. Then some 1/2" A-C for the outer frame and some 1/4" for the back.. Thinner will be lighter...
