My server info:

Thanks
obviously:
yum upgrade mysql*
but, please, don't forget that:
mysqldump

Beyond the basic (correct) answer that pulegium gave...
You are using either RHEL5 or CentOS5; enable your yum system with the IUS Community repository, it's a shared repo (like EPEL) that aims to provide newer PHP and MySQL packages that fit right into your server that was started by Rackspace employees.
Start here: http://wiki.iuscommunity.org/Doc/ClientUsageGuide
While 5.0.51a is the latest Red Hat provides, IUS is providing 5.0.88 as of this writing.
Instructions on handling mysql upgrades, regarding the db itself, are in mysql documentation. When you change minor version (eg. form 5.0.x to 5.0.y) there usually isn't very much to do (if anything at all) - although there can always be some minor tweaks here and there.
Instructions about upgrading a package on your distro are in the documentation of your distro.
All in all, I do recommend you to follow the usual updates that come with your distribution of choice. If they bundle some version of MySQL, stick with that unless you have a very good reason not to do so. For a db server, I'd upgrade the whole system rather than putting an 'external' package in the distro - but that's me.
sudo yum update mysql-5.0.51a
perhaps.
Of course checking that mysql-5.0.51a is indeed the correct name in the yum repositotry for MySQL.
