include jQuery Accordion

I need to use an accordion in a theme and have included the jQuery above wp_head like I think I should:

<?php wp_enqueue_style('http://jqueryui.com/latest/themes/base/ui.all.css'); ?>
<?php wp_enqueue_script('jquery', 'http://jqueryui.com/latest/jquery-1.3.2.js'); ?>
<?php wp_enqueue_script('ui.core.js', 'http://jqueryui.com/latest/ui/ui.core.js'); ?>
<?php wp_enqueue_script('ui.accordion.js', 'http://jqueryui.com/latest/ui/ui.accordion.js'); ?>

The temporary site is located at http://sicklecellcurefoundation.ecoonamoly.com/about/board-of-directors/.

I was trying to link outside of wordpress, because the accordion.js is not included by default, and I am not sure which version is being used.

Any tips would be appreciated.

thanks,
Danny
