Customizing an author page

Hi,

I’ve been struggling with customizing an author page.

How can I add the author information into the query so that the page displays only current authors’ posts?

Wouldn’t 'author' => $wp_query->get_queried_object()->ID work? If so, where and how do I exactly put it?

<?php 

/*
Template Name: Author Template
*/

get_header();
$data = get_post_meta( $post->ID, 'key', true );
$category = $data[ 'portfolio-category' ];
$categoryID = get_category_id($category);
?>

<div id="thumbs" class="gradient">
	<ul>
		<?php $showPostsInCategory = new WP_Query(); $showPostsInCategory->query('cat='. $categoryID .'&showposts=1000');
	if ($showPostsInCategory->have_posts()) : while ($showPostsInCategory->have_posts()) : $showPostsInCategory->the_post();?>
		<li>
	    	<a class="thumbLink" href="#"><?php the_post_thumbnail('fullsize', array('title' => ""));?></a>
	    	<p class="thumbTitle"><?php the_title(); ?></p>
	    	<a class="readMore" href="<?php the_permalink() ?>">Read more &rarr;</a>
	    </li>
		<?php endwhile; endif; ?>
	</ul>
</div>

<?php get_footer(); ?>
