On the Debian portion of the menu in apps --> system you potentially
have 3 GDM related menu items:

GDM setup - For configuring GDM.
GDM flexiserver - For starting additional fullscreen X sessions.
GDM flexiserver in Xnest - For starting additional windowed sessions.

The flexiserver in Xnest item should only show if you have xnest

Not 100% sure, but I think this is a session management thing. When you
are running a Gnome session the shutdown and reboot options show up,
if not they don't.

That's not to say it isn't possible to set it up.

Don't know what's going on there, when you do dpkg-reconfigure on any
of the display managers then whatever you choose as the default should
provide the log in during boot up.

Looking in /var/log/syslog may reveal something.

Don't think this is going to happen, but you never know.

GDM should not have any effect on that. If ksmserver is running the
options should work same as always, if some other session manager is
running then they won't.

Look for something hinky in your .xsession-errors file and in
XFree86.0.log or Xorg.0.log depending on which you are running.
