Replacing 'posts' with 'pages' in this wordpress theme

I'm looking to edit this wordpress theme, but am having trouble figuring out how to get it to do what I want it to.

In the yellow section where it has recent posts, I want that to display pages instead (with a brief excerpt for each page). How would I replace those 'post' spots with 'page' spots?

Any helps is appreciated. Thanks.

 

Replace this

 <?php wp_get_archives; ?> 

Code (markup):

by

[COLOR=black]<?php wp_list_cats('sort_column=name&optioncount=0&hierarchical=0'); ?>[/COLOR]

Code (markup):

In your Sidebar.php in the Theme Folder.
