By default in the theme, if you have any widget stuff, it completely replaces the sidebar. So you would have to add widgets for the Archives, Category list, Links, etc.

However, you can edit the Sidebar page of the theme to add the widget stuff above or below the built-in sidebar stuff.

Look for this code:
<?php /* Widgetized sidebar, if you have the plugin installed. */
if ( !function_exists(‘dynamic_sidebar’) || !dynamic_sidebar() ) : ?>

And its accompanying "endif":

<?php endif; ?>

Either move the first bit so that it’s directly above the "endif" (so that widget stuff goes at the bottom) or move the "endif" stuff so that it’s directly below the first bit (so that the widget stuff goes at the top).

In the WordPress admin panel, click "Presentation" (or "Design" if you are using WordPress 2.5), then click "Theme Editor", then click "Sidebar". Then, remove this section and save the file:

<li><h2>Archives</h2>
<ul>
<?php wp_get_archives('type=monthly'); ?>
</ul>
</li>
