Orange Theme and displaying post date on stories....

I am using the Orange theme and I want to post the date next to stories on the front page with the date of when it was posted much like it on the Grass Theme (http://drupal.amandarodriguez.com/). At first it was not showing the date even though I had told it to display the the date and who posted in the themes admin area. So on the node.tpl.php page I added the code

<?php if ($submitted): ?>
       <?php print $date; ?>
    <?php endif; ?>

So now it is displaying the date but not in a format I want it. What file do I change to display the full day of the week, date, month and year the story is posted like the Grass theme? Also what page do I need to change to add the css to make it display in the way the Grass Theme displays it?

Thanks for any help I receive.
