If you are already running CentOS 5.x, you should just be able to yum update and you'll be fully current. No need to even run it twice. That's assuming that post-5.6 updates are also dropped around the same time as the 5.6 main release.
If the rpm version has been bumped, and/or if yum has been updated, it's sometimes a really good idea to 'yum upgrade rpm' and/or 'yum upgrade yum' first, then do the others. I typically do that, but I seem to remember getting burned by some upgrade of rpm years ago that got that put on my 'do this when a significant update comes along' list. It's right under the 'perform a clone/snapshot' line item (since virtually all of my servers are, uh, virtualized (sorry, couldn't resist), VMware snapshots are easy, pretty fast, and wonderful when things break bad).
The procedure I usually follow:
yum upgrade glibc* yum upgrade yum* rpm* python* yum clean metadata yum upgrade
