Yes. You are correct, in that I looked this up and these are the colors:
The ballast has 2 yellows that go to both prongs at one end of two lamps.
It has 2 reds that go to both prongs of the other end of the first one of
those two lamps, and then it has 2 blues that go to both prongs of the other
end of the second of those two lamps.

I think I just have to remove stuff to see where the ballasts go, but in
looking up how to replace them, I realized that I will never find a 1:1
replacement.

I think it may be "easier" and more cost effective to just replace the
entire assembly. Any suggestions for an inexpensive replacement?

For about $ 20 you can get a single electronic ballast that will run all
4 tubes. Then put in the newer T8 bulbs.

You will have to follow the wiring diagram that is on the ballast as it
will be different from the old one. The new ones are made to fit in the
same bracket/screw holes as one of the older ones.
