1. No
2. Yep
3. Nope, just plug it in, restart and windows will see it. Providing your video card has dual outputs or you have 2 video cards.
4. Depends. 2 20" gives you 3,528,000 pixels to work with, 1 24" gives 2,304,000. 2 24" would give you 4,608,000. I like dual because it makes it easier to move stuff around for organizational purposes.
Right now I have 1440x900 (MBP) and 1680x1050 (Samsung 206BW). Then on Windows I can have 1680x1050 (Samsung 206BW) and 1280x1024 (LG).
My ideal setup would be 1 30" flanked by 2 20" (portrait) for auxiliary things.
