looks like some kind of carbon steerer-safe headset tightened thingamajig. Can anyone tell me if I'm right and how to use it? I couldn't figure it out if it is.

You do indeed need to use that bung. Pop it in the steerer, tighten the bolt with an allen key which will expand it so that it grips the steerer. Fit stem / topcap as normal.

Can't tell you how lucky it was to find it by chance as I was about to strike the hammer!
