You should read the "memory and storage" forum on Anand's. There are lots of SSD tips. Most people think the easiest and best way to install an SSD is just do a clean install of Windows 7. Even a small 30GB SSD will work for a clean install. After this, you just need to use your head, and hopefully have a regular hard drive for storage of large files and programs.
My current Win7 install has quite a few programs installed, not large game files however, and it fits in a 40GB size on my 80GB SSD.
