Same way exactly.

twistd --help should tell you (but, say "twistd --reactor=gtk -y
yourfile.py").

You can have it work both ways, using an if __name__ == '__main__'.
Again, I suggest you read my tutorial, the link to which was on the
previous email (it's on my homepage.) If you want your program to parse
command line arguments this won't work though.

So, you can just use PDB directly, as with *any* python script.
"/usr/lib/python2.2/pdb.py offlineimap.py".
