1. if you can find one, yes it is possible, but to what end? The 8400GS is a low end card that wont see much, if any performance increase from a modded/updated BIOS.
2. It will do neither. It will only increase the amount of air flowing through your case.
Well of course its possible to update your BIOS, but your BIOS has almost nothing to do with your Video Cards, and no, increasing the speed of your fans would not make your system faster, just make it cooler and more stable

Ok, should of clarified, as Atomic Rooster said, it just wont do much for such a low end card, least i doint think it would, i could be wrong though. :/
It won't increase the speed, but will keep it nice and cool. If it doesn't overheat, it won't automatically shut down on you. That can be annoying, trust me. Also, it will make your PC MUCH louder with the fans working harder. Keep it in the middle.
