Twenty-Ten Sidebar

I’ve been trying to get rid of the recent post/comments sections in the side bar of the Twenty-Ten theme. I have also been trying to re-arrange the meta, archives, and categories sections. Also I want to add a tag cloud. Sadly I can’t seem to do these tasks. The side bar ignores my changes unless they are drastically different from what I want. The PHP for the area I want to change reads:

<?php
	/* When we call the dynamic_sidebar() function, it'll spit out
	 * the widgets for that widget area. If it instead returns false,
	 * then the sidebar simply doesn't exist, so we'll hard-code in
	 * some default sidebar stuff just in case.
	 */
	if ( ! dynamic_sidebar( 'primary-widget-area' ) ) : ?>
			<div id="search" class="widget-container widget_search">
				<?php get_search_form(); ?>
			</div>
			<div id="meta" class="widget-container">
				<h3 class="widget-title"><?php _e( 'Meta', 'twentyten' ); ?></h3>
				<ul>
					<?php wp_register(); ?>
					<li><?php wp_loginout(); ?></li>
					<?php wp_meta(); ?>
				</ul>
			</div>
			<div id="archives" class="widget-container">
				<h3 class="widget-title"><?php _e( 'Archives', 'twentyten' ); ?></h3>
				<ul>
					<?php wp_get_archives( 'type=monthly' ); ?>
				</ul>
			</div>

		<?php endif; // end primary widget area ?>

There seems to only be the PHP for the meta, archives, and search bar which I also found strange, does Twenty Ten store the coding for the other parts somewhere else?
Sadly I can’t link to it because it’s hosted locally on my computer. I can post screen shots though if you need them.
