Do the nets make it into the gerber files?? Or would the top copper layer just represent places of copper vs no copper to the board house?

In particular, I want to make a thin rounded-corner rectangle shape in the top copper layer to represent my board outline (the way the board maker likes it). I figure I can make this with four arcs and four straight lines. Alternatively, I could make this with a big polyline, but that would be very tedious if I want smooth corners.

Looking thru a gerber file, I don't recognize net names. So I am hoping that I could make my shape out of 8 pieces and have it equivalent to a single shape.

I didn't understand how net names concern to Gerber files.
If you want to export top copper layer and board outline together, just select two these layers simultaneously on export Gerber dialog window and export them to single file.

I have the same question, but maybe for a different reason.
My fabrication company does electrical tests on the boards before they go to assembly. They claim they do it off the nets in the gerber files, but if there are no nets in the gerber files, what are the basing the connections on?

There is not information about nets in Gerber files. Probably PCB manufacturers use advanced CAM software, that allows to import netlist (or ASCII data) together with Gerber files and analize connections.
