Oh, as far as drivers go, if you install the pgAdmin2, it should install the latest pg odbc drivers for you, if you don't instll the pgAdmin then you can find the drivers at the postgresql site.
I haven't actually configured a connection for anything other than setting up pgAdmin2, but it should be pretty straight forward once the ODBC is installed on the windows side. I have done alot of MSSQL connections with no problems.
Again_good luck...
