Actually, I did not look at the CentOS Cluster Suite tool as I thought it was only available when purchasing a RHEL subscription.
I am currently looking at DRBD and uCARP as this seems to be exactly what I am looking for. Essentially, you have an active and passive server connected back-to-back with an ethernet cable, and your data volume (/mnt, /export, etc) is continually synchronized between the parter pairs. Using DRBD and uCARP, you can have an HA cluster for NFS, MySQL, Apache, etc up and running very quickly. And, it appears MySQL officially supports DRBD clustering. Here are some good links:

Thanks to all who replied...

Once up and operational, this cluster is expected to be 100% hands-off (as in - deployed in the field at remote locations) so reliability is critical. This node will consist of two independent systems connected via back-to-back GigE network interfaces for redundancy.

I was also looking over at RedHat's site recently and read some information on their "Red Hat Cluster Suite" product and was trying to find out exactly how much $$$ it costs to deploy.
