The driveside of the hub/axle is fine. The non-drive side, when I attempt to remove the nut, the piece with the black arrow above it turns in the same direction, so I have to use a 2nd wrench to hold it still while I unscrew the outside nut (red arrow).
When I completely remove the nuts, leaving just the piece with the black arrow above it on both sides of the hub, I'm not sure if I'm supposed to tighten them or not. When I tighten them, hold the axle, and attempt to spin the wheel, the wheel doesn't spin. Does the piece under the black arrow have a name? The driveside one is tight and the non-driveside one is loose, allowing the wheel to spin relatively normal. It seems I can unscrew the piece, but then when I do, the metallic gray piece begins shifting left and right inside the hub when I jiggle it.
I'm wondering if the hubs and bearings need servicing as well, as the rear-wheel doesn't appear to spin as freely as it could.
Looks like the cone (gray thing to the left of the black arrow), locknut (black arrow), axle bolt (red arrow) --

The locknut should not be loosened / tightened willy-nilly. It's responsible for keeping the cone at a particular tightness so that the the bearings in the hub are appropriately restrained. If the cone is too loose, the hub wobbles left and right on the axle. If the cone is too tight, the wheel doesn't turn or turns "grime-ly" as your bearings are being ground down. The right tightness with smooth wheel rotation and no left/right play of the hub can be on the order of single degrees adjustments to the cone. The locknut keeps the cone adjusted that way.
It sounds like you should at least get / perform a cone adjustment. The axle bolt rotating the locknut is a separate (but possibly related) issue that I can't comment on. I can't imagine why the axle bolt would be so far to the left to be pressed up against and rotating the locknut. Hope this helps with at least putting names to metal parts.
