Well, it definitely sounds like you want a TN + Film panel as those are generally the best for gaming and movies. A good MVA/PVA panel would also fit the bill nicely as well as providing you with better image quality and viewing angles, but expect to pay roughly $150 - $300 more.
One thing that you'll probably want to do is properly calibrate the monitor and definitely use the DVI connection if you can. If you can't afford to buy a hardware calibrator (most people aren't willing to drop $150+ to calibrate a monitor), you can use software calibration. It's not quite as effective, but helps immensely as very few monitors come properly calibrated from the factory.
This article on calibration is from TFT Central, an awesome resource for anyone interested in LCD monitors, how they work, and what to look for.
