Hard drive partitioning of a cluster's headnode


I built a HP cluster, but I'm still very ignorant about Linux. However, the headnode has a small partition for Windows XP, and a large Linux partition. Someone advised me to put the users' files on a separate partition, because when we start with serious computations, the output files are really big and it will clutter up everything else.

I have a GParted CD and I used it a while ago when I shrunk the XP partition.
Now, I guess I first have to shrink the existing Linux partition, and then create another partition, and then somehow copy the /home tree onto that. Am I right? How should I go about doing it?

[compchem@gnlserv01 /home]$ df -a

I have 8GB RAM on the headnode, but only 2GB for the swap partition. Is it necessary to enlarge the swap space, and how do I do it?
