The DB topic guide on python.org has some hints and tutorials
about how to use the DB API and there are also a few Python books
which contain chapters about this, e.g. the Python book about Win32

Was the problem related to mxODBC or EasySoft ? Have you read the
mxODBC Configuration Guide by Paul Boddie ?

How about writing down you experiences like Paul Boddie did and
putting the results up on the web somewhere ?! This will help
others configure Python database access more easily.
BTW, I'd suggest asking in a forum like this before taking off
into an uncertain direction. The subscribers on this list do
have a lot of experience and may well be able to point you
to a possible solution.
For the Linux -> MS SQL access I would have pointed you to the
OpenLink/Merant ODBC driver kits which should allow you to connect
from Linux to NT. Another possibility would have been to try to
use a Sybase ODBC driver for Linux -- MS SQL Server's wire protocol
is said to be compatible with Sybase's.
