[Centos] Updating on CentOS-3.3

Sorry to be beating a dead horse to death here... but... in the 
archives, mostly the FAQ is mentioned, but the FAQ seems to be 'coming 
soon'. :)

I just did a clean install of 3.3. I am operating from the command line.

I first mistakenly ran.. been there done that on WhiteBox as well. :(

rpm --import /usr/share/rhn/RPM-GPG-KEY

Got what I understand now is the expected errors.

I then ran

rpm --import /usr/share/doc/centos-release-3.3/RPM-GPG-KEY
I looked and the file is in fact there.

And I'm still getting the errors in both up2date -u and yum update.

warning: rpmts_HdrFromFdno: V3 DSA signature: NOKEY, key ID 025e513b
Error: Could not find the GPG Key necessary to validate pkg 
/var/cache/yum/update/packages/cups-1.1.17-13.3.16.i386.rpm

Thanks for any help. Perhaps one good email clearly explaining the whole 
deal on this would prevent more of these snippets spread across the 
archives, until the FAQ is back up? Maybe? ;)

Thanks for a great release!
