The switches are controlling the voltage levels on the assigned pins just fine now!
One last problem remains though, in that I'm still having trouble receiving input even with the trick above. I tried assigning one of the GPIO pins to LEDG[7] with the idea being that I could feed GPIO[0] back into it and see if the LED would light up. Instead, the programming failed spectacularly, with multiple random hex segments lit up, LEDG[7] lit continuously with no input, and nothing else working. So clearly that was a disaster. Any ideas on where I can proceed next?
