3.  Would a hobbit network test ever initiate a connection using UDP on a high numbered port, like 37383?
No.
BTW, I figured this out.  The UDP connection attempt is a result of having the "trace" option in bb-hosts enabled.  The traceroute will attempt a UDP connection to port 33435 on the failed server, then follow up with UDP conns to ports 33436 & 33437.  The port I listed in my message above was from the Hobbit server, which has varied each time and thus didn't match anything obvious.

I'm just throwing this out there in case someone else runs a tcpdump on their hobbit server, with the "trace" option in effect, and can't figure out why some weird UDP traffic shows up after a system fails the conn test!  ;)
