More Posts from Category below Single Post

Visit http://www.nichedigging.com/amarillorestaurants and click on any single post.

Down at the bottom it lists ‘More Posts’ from the specific categories used in the actual post above. However, this is as far as I’ve gotten with the code:

<h2>More from <?php $category = get_the_category(); echo $category[0]->cat_name; ?></h2>
<ul>
<?php echo $moreFormAuthorCats; ?>
</ul>

Is anyone familiar with this? I was able to change the ‘array’ number to read the different categories for the header, but I can’t get it to show only the posts for those specific categories. At this point, the ‘More Posts’ links do not have to be author specific – just category specific.

Any help?
