Load and interact with a node comments from their related node
Ok so here is one way to do it, it's not very elegant and needs improvement.

I created a comment view that has a page display which gets NID from url so when ajax calling the content with ajax my/url/89 will return the comments for node 89. This works; even Ajax_Comments are working!  

Edit: Ive fixed it so it will cache the data for the user, so when traversing the gallery, it does not load the data ad-nauseum. It stores in .data and pulls it back in if the user has already viewed it.

Anyway, even though this works I feel it needs a lot of improvement and/or different approach.  Below is some of the related updated latest code.

$(function(){

  // Override the default behavior of all `a` elements so that, when
  // clicked, their `href` value is pushed onto the history hash
  // instead of being navigated to directly.
  $("a.thumb_link").click(function(){
    var href = $(this).attr( "rel" );

    // Push this URL "state" onto the history hash.
    $.bbq.pushState({ image: href });

    // Prevent the default click behavior.
    return false;
  });


// Keep a mapping of url-to-container for caching purposes.
  var cache = {

   '': $('#gall-default') // If url is '' (no fragment), display this div's content.
  };

  // Bind a callback that executes when document.location.hash changes.
  $(window).bind( "hashchange", function(e) {
    // In jQuery 1.4, use e.getState( "url" );
    var url = $.bbq.getState( "image" ); //Get State from the above push "image"

    // In this example, whenever the event is triggered, iterate over
    // all `a` elements, setting the class to "current" if the
    // href matches (and removing it otherwise).
    $("a.thumb_link").each(function(){
      var href = $(this).attr( "rel" );

      if ( href === url ) { //Mark the active thumb and launch its content!

            $(this).addClass( "current" );
            $("#gall-default").css("display","none");
            //event.preventDefault();
            var $this=this;
            $bgimg.css("display","none");
            $preloader.fadeIn("fast"); //show preloader
            //style clicked thumbnail
            $outer_container_a.each(function() {
                $(this).children(".selected").css("display","none");
            });
            $(this).children(".selected").css("display","block");
            $outer_container.data("selectedThumb",$this); //get and store next image and selected thumb 
            $bg.data("nextImage",$(this).next().attr("href"));  
            $bg.data("newTitle",$(this).children("img").attr("title")); //get and store new image title attribute
            itemIndex=getIndex($this); //get clicked item index
            lastItemIndex=($outer_container_a.length)-1; //get last item index
            $bgimg.attr("src", "").attr("src", $this); //switch image

            //set context for node load bits
            var node = $(this).attr( "node" );

            $("#ajax-div .inner").empty();


             if ($(this).data('comm.cachedHtml')) {
                  $('#ajax-div .inner').html($(this).data('comm.cachedHtml'));

             } else {

                var toLoad = $(this).attr('node');// Get the URL of the clicked link.
               $.ajax({ // Now load the content
                    url: toLoad,
                    cache: true,
                    beforeSend: function () {
                    $("#preloader2").fadeIn("fast");
                },                  
                    success: function(data) {

                      $('#ajax-div .inner').html($('#content', data));// Inject new content 
                      $("#preloader2").fadeOut("fast");     
                      $(this).data('comm.cachedHtml', data);
                      Drupal.attachBehaviors('#ajax-div .inner');
                    }
                });


              }

      } else { //Un-Mark Thumb &amp; other deselecting 
         $(this).removeClass( "current" );

      }
    });

    //do something  here..
  });

  // Since the event is only triggered when the hash changes, we need
  // to trigger the event now, to handle the hash the page may have
  // loaded with.
  $(window).trigger( "hashchange" );
});
