Field Delimiters and Storing DB inside it???

I assume you want me to open up a language file and put these strings in there.

Correct.

Where do I put these strings? which file?

Review your documentation (available for download in Advanced downloads) regarding language usage.

And won't that effect the whole site, for example if someone puts in 4 identical digits on a separate field wont that spit out the URL value as the output based on the language file?

If it calls the define it will. You can try using cbteamsplugin method as well which is as follows that only affects CB and only when called directly from API.

'1234' => 'Value 1',
'5678' => 'Value 2',
'9012' => 'Value 3'
