The very first thing you should do is to up2date your install (including the latest kernel release for your distro). This is a must!
Get the kernel-sources (the very same version of your new kernel), gcc and make packages.
And before someone else says it, please read the release notes. They have a nice section with step by step instructions to install the drivers. If you get stuck, come back with specific questions.
Please, help us help you.
