Looking for driver for internet, isight, etc.

I followed the download instructions for Boot Camp for installing Windows 7 with Snow Leopard and formatted my disk just as instructed, as well as the MBRFat usb. I have reloaded Windows 7 three times with the USB in place, but still cannot get these three drivers to work. I've tried uninstalling and detecting again. Where can I get the correct files? I read somewhere that there might be a typo?

How much does Apple charge for help once Apple Care runs out?
