under normal circumstances, /etc/hosts should have only two entries.   
the exception to this may be if you're using NFS, then hosts should have 
any NFS clients and servers names (unless you do your NFS mounts by IP 
address, something I don't really recommend).


    127.0.0.1                      localhost localhost.localdomain
    xxx.yyy.zzz.www       hostname hostname.domainname.com


/etc/aliases would contain any email aliases you want, for instance, if 
you want all mail to root to go to local account jamest...

    root:      jamest



there's usually a bunch of sorta stock aliases, like postmaster, etc, 
these usually go to root, which in turn you forward to whomever.
