It looks like this is running an old version of the server.  I've notified the 
THREDDS group here of your problems.  See my comments below though:

This is a bug.  Hopefully updating the server will fix that.

A configuration problem.

That's expected and the same on other servers.

I take it you need more than what the 80km CONUS covers.

That should work (with the caveats above).

No problem.
