Almost any card with dual video outputs can do the double monitor dance, and since you don't game at all you can afford to go cheap. Video cards don't really affect movie viewing so you don't even need to worry bout it.
No, I didn't realize you were with Vista. The 6600 leaves alot to be desired of a gaming card but as you aren't interested in that it's a fine choice.
Newegg has better prices than tigerdirect unless you live in another country than usa

The 6600 will work fine with vista. You could spend extra to get a 7600gt, but as you said yourself you aren't planning to game so it would be a waste. It's up to you of course.
