2008R2 Remote Desktop - Start menu customisation issues

I'm in the process of moving a client from Server 2003 to Server 2008R2 Remote Desktop Services and I've hit the following issues to which I can't find a solution:

1. How can I remove the Search Everywhere box from the Start Menu for most users.

2. How can I pin program shortcuts to the Start Menu using GPP?

3. Is there a way to give users access to printers without also exposing devices?

Thanks
