Just to complement Saurabh's answer:
Any time you want to relocate an element on a page, the jQuery functions 'insertBefore' and 'insertAfter' can be of great use. For example, putting the progress bar above the navigation arrows only requires this one line of code:
<script type="text/javascript">
$(document).ready(function(){
$('.progress_bar').insertBefore('.submit_div');
})
</script>
