I am trying to setup emacs for python development at place of work.  I would
like to push for emacs culture over eclipse and so want to know what to do
for the python-related emacs goodies.

I need things like completion and help. I believe there is some way of
customizing eldoc to give 'hover tips'.
Also anything else that is there -- gud support?

I am running debian etch and am using the python-mode package that comes
with debian.  emacs-wiki says there are two python modes.
Which this one is I am not sure.

locate python-mode.el
gives me
/etc/emacs/site-start.d/50python-mode.el
/usr/share/emacs/site-lisp/python-mode/python-mode.el
