I highly recommend adding custom sidebars and footer widget areas to your site. This does two things. 1) Allows you to not have to have the same sidebar throughout your site. and 2) Put targeted content in your sidebars to compliment the content on specific pages and/or posts. It allows you to assign custom widget areas to pages, posts, taxonomies, templates and archives.
