Partitions

After I sort out a replacement CPU (hope it didn't damage the mobo), I'm going to be reformatting the hard drive. I'd like to get multiple hard disks, but I already have 250GB and... ...you see where I'm going with this.
With Windows XP and a 250GB Hitachi drive, what have I got to worry about? Are there multiple methods of doing so? I've only heard of FDisk. Is partitioning beneficial other than logistical reasons? Harmful? Should I make provisions for anything special? I seem to recall partitioning for virtual memory or swap file. Does this ring a bell? Who shall run the gauntlet today?

Planned:
Reccomendations?
