1)Please confirm that the language plugins can basically be considered like the translation dictionary for the machine language to front-end language (stupid expression but I forgot the term) and
It's just like Joomlas language files except as faster PHP arrays instead of INI files. Because it's a PHP array we can support a lot more functionality that INI can't provide like multiple keys, key overriding, etc.. It loads the language plugin, loads the strings into the language array, when the key is requested it displays the matching value.
2) What are numbers at the end of the CAPITALS? Or are they just differentiators?
It's just a hash we generate with our language parsing. You do not need to supply a hash for your custom strings.
3) Just to confirm... if all two questions above are yes, I change the stuff after => ?
Yes, you change the value of the key value pair.
4)How can I find the "machine language" of the stuff I want to change? (in this case all of the CB emails). Any shortcuts than going through all the language files?
No idea what you mean by machine language. All of CBs language strings are in the language files. You'll need to search the files for strings you want to change. This is best done in an IDE (phpstorm, netbeans, etc..) to avoid making PHP syntax errors (unescaped quote, etc..).
