To be honest, I would just install 11.0.5058, I am sure the difference is very minor.
Finding the correct driver on Microsoft website is always a challenge. I think you will need to look at their SQL Server 2008 Service Packs, try SP3.
I don't know for sure, but the client software is often installed along with the db. Or is available as a link in the help for the db. Even FM does this for connecting to it via ODBC.
