"Prop..." Do you load in a primitive, then parent it to, for instance, Lower Jaw? Then turn the prop into a control?

Yes. You can also spawn a prop with the grouping tool - select a cluster of polygons in the chin, or just one polygon even if that's all you need - spawn a prop from that selection, then convert it to a control prop for the lower jaw. You can also set the display so that it is an outline or transparent, whatever you prefer.
