Would it be fine to run a production server with KDE? Also is there a site/forum/ which I can refer to which packages are a necessity to run a server e.g. mail, web, etc

Linux servers are running usual without GUI, instead they are using SSH or a web based remoting tool like Webmin - http://www.webmin.com

Here are some example packages for a server:

Webserver:
Apache

Mailserver:
Sendmail or Postfix

Databaseserver:
MySQL, PostgreSQL

DNS server:
BIND

FTP server:
ProFTPD
