I'd consider the most valuable things to know about would be the nature of an 
assortment of 3rd party yum repositories (i.e. EPEL makes an effort not to 
overwrite core packages but probably won't have everything you want), how to 
find and install their *-release packages, how to use yum to search and install 
things from them, and that most of them should left disabled in the yum 
configuration so they don't affect things unless you explicitly enable them on 
the command line for a search or specific package you want.

Oh - and how to install and use freenx/NX for remote access.
