Does "direct connection" work?

Yes, you're correct.  I'll try to work on it whenever I get some round
tuits (not likely to happen soon, though).

That won't help much, because setup simply delegates to IE (invokes a
Windows call that retrieves the URL).

Hmm, the above URL is exactly the one it uses for retrieving the mirror
list.  I'm not sure what information setup could output -- perhaps you can
grab a debug version (from the snapshots directory) and step through it in
gdb (once you get Cygwin installed, that is)...

Yes, there are a few ways.  First, I'd save the mirror list as
/etc/setup/mirrors-lst (prime the cache, so to say) and run setup again
(hoping it can then access the individual mirrors).  Or you can use setup
on another machine in download mode, copy the whole directory tree to your
machine, and then tell setup to "Install from local directory".  Another
way is to mirror the repository on some site you *can* connect to and add
that as a mirror explicitly.

It would still be interesting to see why "Use IE5 settings" fails on your
machine while you can retrieve the mirror list via IE itself...  Do you
have to log in to your proxy?  If so, did you run setup after you logged
in via IE?
