How would you put together a new install

[AsProductions]

I've just completed the server install of FC3 text mode. No GUI for me. Maybe in the future but not yet. I would like to configure this server as a mail server (either SendMail or PostFix, I've never used postfix however), DNS, Samba, SFTP, DHCP for starters. I'm hoping someone could offer some advice as to what to start with first. I just completed the install and am now at the command prompt but I'm not sure where to begin or if there is any recommended "tweaking" to be done. How do you approach a fresh new system configuration process?

Thanks and Salute! :)
