Although I would seriously consider the ati HD4870, it should be cheaper than both preform around the same level as the 9800gtx which will leave you extra money to put someware else.
There's not a massive differnce between xp and vista 32bit versions, vista looks pritty and is needed for dx10. (although if you're used to xp trying to find things in vista is a pain.)
However if you can get it vista 64bit is what you want to go for, the reason is that that 32bit OS can only make use of 4gb, under 4gb, to be exact 3 and a bit gb (to save arguement)
Don't really know enough about monitors esp larger ones, general advice would be
22" rather than 20" (same resolution but larger is nice)
Check the brands warranty, 3year is common, "on-site" is better than "return to base" basically; on-site, they send out a courier to give you a new one and collect the old one. Return To Base, you have to ship it to them at your expense.
Faster response and higher contrast is good, but beware they lie! as with other things there are ways they can clame higher/lower numbers than is actually the case. however 5ms response fine, as is 1000:1 contrast. extra is a bonus but not vital.
You can always try going to a computer shop or electrical shop (in the UK we have PC world and Curries and such) don't go to buy but to have a looks at them and see what you think.
P.S.
I looked up the antec 300 gamer, seems to be Newer than the 900 (note there is an older antec 300 slimline, but thats a totally differnt case)
It looks like a smaller simpler version of the 900, it does have the same 120mm+140mm rear+top fan combo as the 900, slots for 2x120mm front and 1x120mm side fan (although the fans are not supplied unlike the 900)
So the cooling is the same, just smaller inside and no removeable drive bays. (although one review said a 8800gts just fits inside so a 9800gtx might be very tight)
P.P.S.
The PSU in the Sonata is an Antec Earthwatts 500w, which is made by seasonic, it's a decent PSU if a little plane looking.
It should be enough to power your PC with the parts you listed.
