I think all you want to really do is dynamically generate a mapfile
based on the thematic classification you want to apply to the
polygons (we have to use SQL Server in a similar manner, and that's
how we do it.)
Look at the MapServer Website under classes and look for an example
maybe with a regex (to identify the field in the dbf that matches
your database).
We use either perl or php to either replace placeholders in a
template file for cgi applications, or (using mapscript) write the
mapfile from scratch.
If you are still having trouble this is probably a better question to
direct at the MapServer users list, as it sounds as though you have
ms4w working OK.
cheers
