Is this jquery properly optimized or duplicated?

Hi all, is this all fine now or am I duplicating some scripts? Thank you!

<script type="text/javascript" src="/js/jquery.min.js"></script>
<script type="text/javascript" src="/themes/development-bundle/ui/jquery.ui.core.js"></script>
<script type="text/javascript" src="/themes/development-bundle/ui/jquery.ui.position.js"></script>
<script type="text/javascript" src="/themes/development-bundle/ui/jquery.ui.widget.js"></script>
<script type="text/javascript" src="/themes/development-bundle/ui/jquery.ui.dialog.js"></script>
<script type="text/javascript" charset="ISO-8859-1" src="/js/fns_index.js"></script>
<script language='javascript'> 
$(document).ready(function(){
	$('#debug').ajaxStart(start_window);
  $('#debug').ajaxComplete(stop_window);  
});
</script>

No duplication seems to be occurring there, so it’s okay for development purposes.

When you roll it out as a final page ready for production, you should combine several of those script files together in to just one file, to help reduce the number of http requests that are made when loading the page.

Thanks Paul!
I like your tag line about java and javascript, yeah Java died a death didn’t it! I’m lucky I never learnt it, I remember back in the day everything web was going to be java applets this java applets that. Anyway I digress, thanks again!
