You can use the jQuery UI Progressbar plugin. As your page loads the data it needs, update the value of the progress bar.
You sir need to use $(document).ajaxStart() and $(document).ajaxStop() to achieve that with jQuery.
http://api.jquery.com/ajaxStart/
http://api.jquery.com/ajaxStop/
This might be not exactly what your looking for, but it will help you get started: http://yensdesign.com/2008/11/how-to-create-a-stylish-loading-bar-as-gmail-in-javascript/
You will need to use a mix of jQueryUI ProgressBar and jQuery FancyBox which can hold content (like a progressbar).
