PC Game Controller Question

I want to buy the Logitech ChillStream PC game controller. I want this specific controller because it has the same layout as the Xbox 360 controller, but is much cheaper (from Ebay).  My computer is running Windows 7. I was wondering if there was a program that I can download, or that comes with the controller that lets me customize it for use with different games. Maybe let me navigate the computer with it, then choose or customize a new profile to play the new Split/Second PC game.
