3Gigs of RAM isn't over kill for Windows XP SP3. My wife's computer has 3 gigs of RAM and has plenty of room for other applications. She is a gamer, and she DJ's on a game called Second Life. THat game takes up a lot of RAM and so does her DJ Program.
Leave your pagefile settings alone, and let windows handle it. Setting your page file to none can cause serious adverse effects when your RAM gets all used up, and this can include BSOD's, Lock ups, and shutdowns.
I say 2Gigs is the bare minimum for any operating system out there.
