new to LCDs, Help me choose!

hello,
I'm in need of a new monitor... and I thought I would go with an LCD this time, because I barely have any desk space left, and I have to get rid of this 19" samsung 997df crt.
But anyways, back on topic.. i'm fairyl new to them, but I know a low response time is good. But i'm not really sure about some of the words, like... what is ghosting? well yeah,

I'm usually on the computer atleast 8+ hours aday and I'll need this monitor to
a. surf the net
b. chatt on msn
c. alittle adobe photoshop
d. lots of games, mainly FPS & rpgs
e. watch movies

I know the lcd won't be able to do all of it, especially the movies part. but as long as I don't go blind, or it straining my eyes alot, it's cool.

my price range is roughly 300usd +s&h, but I've chosen and reviewed some of these myself.

1.SAMSUNG 931C High Glossy Black 19" 2ms ( used in this year's WCG )

2.ViewSonic VX922 Black/Silver 19" 2ms ( good reviews )

3.BenQ FP93GX Black 19" 2ms ( used at CPL winter )
http://www.newegg.com/Product/Prod [...] 6824014111

Now, i'm still not really sure about ALL the specs in these lcds, like is the contrast ratio good? and how do I know if the monitor will be really bright?

Hopefully you guys can explain to me, and help me choose out one of these monitors, or suggest one


thanks in advance
