I've done point upgrades on centos5 LAMP boxes many times and have never had an issue.  I have always trusted that RHEL wouldn't want to make silly changes that would affect hosted sites, and for centos to maintain that, and it has worked out for the most part

the primary caveat would be that we developed our own code and didn't do anything overly complicated, so if you're hosting a bunch of wordpress/drupal/phpBB/etc, YMMV


are you preventing php updates via yum.conf or other similar mechanism?  I've always had those components updated along with the rest.  the test plan we had was to update the dev servers first because the developers were always in it, and if nothing went sideways, to update prod
