Best YUM configuration?

[colson]

Hello!
  I'm a new FC5 user, migrated from Mandriva after its implosion.  My 
experience with package management comes mainly from their URPMI 
system.  As such, I'm wondering -- what are the best YUM repositories to 
use?  From what I've read so far, there are two main groups beyond the 
default ones which are mutually exclusive.  You can either go with 
livna/fedora.us, or you can go with the dag/freshrpms/dries/newrpms 
group.  What are the relative merits of the two, and what would the list 
recommend?

As a side question, I haven't been able to find a package for lilo in 
any of the standard yum repositories, and it doesn't appear to be on the 
system (it wasn't an option in the installer).  Does such a package 
exist, and if so, where?
