I haven't seen a clear answer to your question so I thought I would give it a try. Yes you can run any 9.2 tools with 9.1 apps. You won't get all of the new functionality but it will work. The problem comes in with your windows 2008 server. The latest versions of 9.2 tools don't support anything older than 2012 R2. The oldest supported SQL server is going to be 2014.
