Jsut wrap the data in a call to jquery and you can use it like you would normally:

$.get
    (
        "JQueryPage.aspx",
        function(data) {
            var dataDom = $(data);
            $(someSelector, dataDom).each(function(){
                alert($(this).html());
            });
          } 
    );

1. If the html markup of JQueryPage.aspx is valid xml, you can use dom parser to get the required div.
2. It depends - if all you want is to add the retrieved html to the existing DOM using a call to document.appendChild, yes. But if you need to parse and read values from the retrieved data, no, this is not. Pass data as a JSON string or xml.
