Don't think of 5.0 and 5.1 as different distros.  They are the same distro.

Think of it as a bunch of non-critical updates that were withheld from the
regular update cycle, tested as a set, and released all at once with a new
installer image.  It is just an update, analogous to a Windows service pack.

Think of RHEL5 as the distro, evolving through time, and 5.1 as a well-tested
snapshot of RHEL5 at a particular point in time.  

A regular 'yum update' will bring in all of the new updates.  There is no need
to reinstall the OS.
