I would highly advise simply paying the money for a RAID Controller card 
to handle all of this for you. You mentioned that you do not have 
physical access to the server, so the Raid card can easily handle hdd 
failures and send you an email letting you know that you need to replace 
the other drive.

As above, we use the 3ware 8000 series raid cards because of its great 
track record (we always have and always will use 3ware) and freebsd / 
linux support.

Never a good idea to run X when you dont need to. All Administration can 
be done via config files on the command-line and any system-config gui 
programs usually have a commandline replacement anyway. But if you 
really wanted X check out 'yum grouplist' and 'yum groupinstall "X 
Window System"'
