"I tried using node names as a workaround - I went through and named all of the nodes I wished to see, I just named them their respective node numbers - but they don't show up at all when I hit 'names only.'"

For above problem, first select the "all" under show restraints number then select "names only". It is necessary for "all" the restraint numbers to be visible for "names only" to work for some reason. It will not work if you have either none of restraint numbers shown or some of the restraint numbers shown.
