Simple.

Nah, just break it down to individual steps. Say for step 4:

1) create a simple HTML form with fields for the info you want to save
2) write the backend code for the form submission (parse and write the
     parameters to the DB)
3) test, adjust as necessary
4) write your mootools-based method to gather that form data and
     submit via XHR request
5) attach onsubmit event handler to "save" button to invoke that
     method and hide the div in question
6) test

and done! Those are all pretty straightforward, the first 3 being what
you'd have to do if there were no such thing as AJAX. Except #2
doesn't need to return a complete page, just status, or a message,
or whatever you want.
