Have you tried looking at the Red Hat installation manual? If you don't know how to get there here is a link: http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/install-guide/s1-d iskpartitioning.html
Be sure to read everything including in the Appendices mentioned. That should give you an idea (with diagrams) on how to partition.
I personally used RH8 & RH9 with the same partitioning scheme. My 256MB RAM m/c with the spare 8 GB distributed over 2 HDDs is divided into 512 MB <swap>, 2 GB for / file system, 3 GB each for /home & /var file systems.
