Keys controlling brightness, sound, etc not working!

I've had my MBP since June and all of a sudden, the keys controlling the brightness, volume, backlight, etc. don't work (none of them do).
And when I go to my settings to check under "keyboard", I get the rainbow wheel cursor (if this is related).
Help!

 

Thanks, I'll try that, but now the power button (to get the shut down/restart window) isn't working either, is there any other way to turn it off?

Edit: Just realized that if the power button doesn't work, it won't turn back on either. I guess I bring it to the Apple store (still have AppleCare)?
