I need help validating

Here is my site.

I have six problems.
Here is the code that I think is giving me the problems. (side bar)

<div id=”tek_sidebar”>

• <h2>Recent Posts</h2>

<?php $myposts = get_posts(‘numberposts=3&offset=1’);foreach($myposts as $post) :?>
• “><?php the_title();?>

<?php endforeach; ?>

• <?php wp_list_bookmarks(‘title_li=’); ?>

• <h2>Meta</h2>

<?php wp_register(); ?>
• <?php wp_loginout(); ?>
• Valid <abbr title=”eXtensible HyperText Markup Language”>XHTML</abbr>
• <abbr title=”XHTML Friends Network”>XFN</abbr>
• WordPress

<?php wp_meta(); ?>

<script type=”text/javascript”><!–
google_ad_client = “pub-9764894583622414”;
/* 120×600, created 2/21/09 */
google_ad_slot = “3524975879”;
google_ad_width = 120;
google_ad_height = 600;
//–>
