I do not know if the standard xfs modules in extras will work or not. 
You can boot the CD and try to install them.

There are xfs modules and tools for centos in centos-extras ... so you 
can install them for the main kernel.

XFS is not supported by Red Hat ... and it does not recover from loss of 
power very well.  The only way I would recommend XFS is if your have 
tried to run it on ext3 and it will not work without the performance 
increase you can get with XFS.  (All the performance in the world does 
not matter if you loose your partition on a loss of power).
