If you decide to go with RHEL6, xfs is a good bet for making one big
filesystem. We have a setup similar to what you're describing and have
had very solid stability and performance using xfs (default filesystem
and mount settings.) As far as I can see (and knocking on wood), xfs is
now a lot less flaky than it seemed to be in the past.
