Normaly, the Vista64 drivers should work for you.
Normaly, ANY programms and ANY drivers made for Vista sould run under Windows 7.
You can check this site:
http://www.driverheaven.net/
It's a repository of drivers for just about everything. It also contains some custom and optimised drivers.
You never need to partition to install any drivers.
On the other hand, it's good to partition your drive, or have 2 or more drives, to physicaly separate your datas from the OS.
That way, if something realy bad appens and you need to reformat and reinstall the OS, you don't need to backup all your datas.
