How can I do this?
Make a custom loop to display the content you’re looking for.

something like the following should do the trick:
<?php if ( have_posts() ) while ( have_posts() ) : the_post(); ?>
<h2><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>
<?php endwhile; ?>
Which a theme, plugin, filter… which?
Kinda depends on how / where you want the data to display and what you’re comfortable with. here’s a quick look at creating custom page templates and modifying the loop:

Articles are published… They have headings and content, etc.
The requirement is to have links to the last 5 articles on a different website. A simle list a links, nothing more. Currently i’m using PERL to parse the XML word press creates and posting the links on a secondary site. This works fine. But, the boss would rather eliminate the need for this extra script. So i’d like to do this within word press.
