I use it in this way:
$("#someelement").load("/controller/action div.index");
loads html content of div.index in #someelement

You can handle it better with $.post / $.get handling the html response
$.get('controller/action', function(html){
var myHtml = $(html);
$("#something").replace( myHtml.find("#something").html() );
});

This works faster if you create an empty layout and print only the
$content_for_layout, I use it with a custom extension
eg. controlller/index.dhtml give me only the action response, without
the whole layout code around.

I suggest you to look at the new -cool- templating system (from 2.1 I think)
