I've just installed CentOS 5.6. What would I get if I upgraded to 6? Would I have to reinstall all applications or could I just restore my /etc and /usr directories and do an update?
Well, CentOS 6 is likely to be somewhat different than 5.6 -- lots of stuff has changed. You would get newer base versions of various packages and a newer base kernel. Otherwise it depends...
You'd have to do a fresh install, and then using a backup of your /etc as a guide, re-configure everything. If your system works just fine with 5.6, *I'd* say leave it alone for now. I am certainly not in any hurry to upgrade.
I have written a set of bash scripts to do just that, ie a fresh install and configuration. They are highly extendable and configurable, and written in a modular fashion. Originally for Fedora to deal with the twice yearly upgrades, but I have also used them for installing Centos 5.5, which appears to have now upgraded itself to 5.6
