Jquery, PHP, AJAX, paginated form submission tutorial?

Hello all,

I am hoping that someone may be able to point me in the direction of a tutorial that goes from beginning to end and covers the topic of Jquery, PHP, AJAX and a form that updates a specific DIV/AREA with new data pulled from a mysql database on submit.

*That last one is the kicker.

Basically, I have a comment form that I am trying to make more dynamic. I want the form to update a specific area of my page when I submit it. The other tricky part is that the form will have to do this while also paginating the results in that area. For a quick and simple example, check out how Kongregate's comment feature works. I WANT THAT EXACTLY, but I want it to use jquery.

So Far I have come up with this:

var options = { success: postCallback};
	
	function postCallback() {
		alert("The comment was added");
	}
	
	// attach handler to form's submit event 
	$('#commentForm').submit(function() { 
	    // submit the form 
	    $(this).ajaxSubmit(options); 
	    // return false to prevent normal browser submit and page navigation 
	    return false;
	});

Code (markup):

That code successfully submits the form but it does not refresh the DIV which contains the paginated results pulled from my MYSQL database.

Please, Help!!
