Customizing sidebar widgets…

I’m running the latest build of WP and have created my own theme/design.

What I’d like to do is customize how the links/blogroll links appear and also the latest posts. Right now, my comments page is the simple/standard comments page that comes with the WP Classic them:

<!-- start sidebar -->
		<div id="sidebar-wrapper">
			<div id="sidebar">
				<div id="sidebar2">
					<div id="sidebar3">
						<?php 	/* Widgetized sidebar, if you have the plugin installed. */
		if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar() ) : ?>
	<?php wp_list_pages('title_li=' . __('Pages:')); ?>
	<?php wp_list_bookmarks('title_after=&title_before='); ?>
	<?php wp_list_categories('title_li=' . __('Categories:')); ?>
 <li id="search">
   <label for="s"><?php _e('Search:'); ?></label>
   <form id="searchform" method="get" action="<?php bloginfo('home'); ?>">
	<div>
		<input type="text" name="s" id="s" size="15" /><br />
		<input type="submit" value="<?php _e('Search'); ?>" />
	</div>
	</form>
 </li>
<?php endif; ?>

			</div></div></div><!-- #sidebar divs -->
		</div>
		<!-- end sidebar -->

Right now, the links are displaying like:

<span class="widget widget_links"><h2>Herd Links</h2>
	<ul>
<li><a href="https://www.site1.com" title="Site1 Title" target="_blank">Site1</a></li>
<li><a href="https://www.site2.com" title="Site2 Title" target="_blank">Site2</a></li>

	</ul>
</span>

What I am wanting to do is do it like this:

<li><a href="https://www.site2.com" title="Site2 Title" target="_blank"><strong>Site2</strong><em>Site 2 Description</em></a></li>

	</ul>
</span>

Where can I edit the code to get it this way?
