That should do it already actually, though to be frank, I'm not fully knowlegable on all the potential conflict types between Prototype and jQuery. Does the prototype script reference (<script type="text/javascript" src="lightwindow/javascript/prototype.js"></script>) on your page proceed or follow the jquery.js reference?
Regardless, one thing you can try is replacing the jQuery reference to use the latest version instead:
Code:
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
