I think we should raise a Feature Request in the bug tracker to show Client Template ID & Server ID in the lists. If not, the only way to be sure you've got the right ID's would be to look in the database.
Also, can you clarify what this section does:
ISPConfig Server Settings (Syntax:WebserverID,DBserverID,MailserverID,DNSser verID)
and how does that relate to ISPConfig Server ID?
I assume Server ID is the field that specifies which Web Server to setup the site on, or is this the one with the Control Panel on?
