[Plugin: WordPress.com Popular Posts] Implement the plugin on the sidebar

Hi,

How to change the following code in order to display WordPress.com Popular Posts? I’m not good with PHP.

<a name="popular" id="popular"></a>
                                <ul id="tab-pop" class="list" style="display: block; ">
                                    <?php $result = $wpdb->get_results("SELECT comment_count,ID,post_title,post_excerpt FROM $wpdb->posts ORDER BY comment_count DESC LIMIT 0 , 8");
										foreach ($result as $post) {
										setup_postdata($post);
										$postid = $post->ID;
										$title = $post->post_title;
										$commentcount = $post->comment_count;
										if ($commentcount != 0) { ?>
										<li><a href="<?php echo get_permalink($postid); ?>" title="<?php echo $title ?>">
                                        <?php if ( get_post_meta($post->ID, 'Thumbnail', true) ) { ?><img src="<?php bloginfo('template_directory'); ?>/timthumb.php?src=<?php echo get_post_meta($post->ID, "Thumbnail", $single = true); ?>&w=120&h=68&zc=1" alt="<?php the_title(); ?>" /></a><?php } ?></a>
										<a href="<?php echo get_permalink($postid); ?>" title="<?php echo $title ?>" class="tabtitle">
											<?php
												if ( strlen($title)> 32 ) {
                                        		 	echo substr( $title, 0, 32 ). "...";
												 }
												else {
													echo $title;
												}
											?>
                                        </a>
                                        <div class="desc"><?php if (get_the_excerpt() != "") {
												echo limit_words(get_the_excerpt(), '30'). "...";
											 }
											 else {
											 	echo limit_words(the_excerpt(), '30'). "...";
											 }
											?></div>
                                        <div class="meta"><?php the_time('l, F j, Y'); ?> <?php the_time('G:i'); ?> - <a href="<?php comments_link(); ?>"><?php echo $commentcount ?> Comment(s)</a></div>
                                        <div class="fix"></div>
										</li><hr />
									<?php } } ?>
                                </ul>
                                </div>
                                <div>

Thanks in advance
