Ok thanks guys, I got everything working now. The thing with Netgear was that 'modprobe' didn't want to work (don't know why) but after a restart it worked and so I could configure it, even SSID is working.

After I got internet I just ran YOU and the sound was back and the drivers for Nvidia were set up so I have 3D support now.

O yea and the mouse - I just reinstalled the drivers and its working now.
