Sidebar Issues

Hi all, this has probably been done to death and back but I cant seem to find what I am looking for. Probably because I am wordpress and php newb.

Ok, I have:

<div id="sidebar">
<?php if ( !function_exists('dynamic_sidebar') || !dynamic_sidebar() ) : ?>
 <div id="about" class="entry">
  <h2><img src="/image/textimage/About/TRASHED/18/fff" alt="About" /></h2>
  <p>This is my blog.</p>
 </div>
 <div>
  <h2><img src="/image/textimage/Archive/TRASHED/18/fff" alt="Archive" /></h2>
  <ul>
   <?php wp_get_archives('type=monthly'); ?>
  </ul>
 </div>
<?php endif; ?>
</div>

What I want to achieve is widgets added in the admin section to have the same markup.

<div id="about" class="entry">
  <h2><img src="/image/textimage/About/TRASHED/18/fff" alt="About" /></h2>
  <p>This is my blog.</p>
 </div>

I would also like the word about to be replaced with the widget title. I cant seem to change what is output from the default list style.

I have `<div class=”rightColumn”>
<?php get_sidebar(); ?>
</div>` in my main index template.

Thanks for your help
