Where to put code in a Page Template to fetch Category Posts

Im trying to create a new Page Template (first one) that displays the posts from a specific category(not full posts, just excerpts).

Now I have been looking at Page Template Codex on what code to us, just since i’m new to this, what part of it do I have to adjust to fit my theme?

So far I have copied my page.php and I am wondering where I put the code to fetch the category, here is my Theme page so far(All i have done is change the name at the top and touched nothing else)

/*
Template Name: Podcast Main
*/
get_header(); ?>

	<?php
	global $wp_query;
	$postid = $wp_query->post->ID;
	if ( get_post_meta( $postid, 'post_featpages', true ) == "Yes" ) { ?>
		<?php include (TEMPLATEPATH . '/featured-pages.php'); ?>
	<?php } ?>

	<div id="page" class="clearfix">

		<div class="page-border clearfix">

		<div id="contentleft">

			<div id="content" class="clearfix">

				<?php if ( function_exists('yoast_breadcrumb') ) { yoast_breadcrumb('<p id="breadcrumbs">','</p>'); } ?>

				<?php include (TEMPLATEPATH . '/banner468.php'); ?>	

<?php if (have_posts()) : while (have_posts()) : the_post(); ?>

				<div class="post clearfix" id="post-main-<?php the_ID(); ?>">

					<div class="entry">

						<h1 class="page-title"><?php the_title(); ?></h1>

						<?php if ( get_post_meta( $post->ID, 'video_embed', true ) ) { ?>
							<div class="single-video">
								<?php echo get_post_meta( $post->ID, 'video_embed', true ); ?>
							</div>
						<?php } ?>

						<?php the_content(); ?>

						<div style="clear:both;"></div>

						<?php wp_link_pages(); ?>

					</div>

				</div>

<?php endwhile; endif; ?>

			</div>

			<?php include (TEMPLATEPATH . '/sidebar-narrow.php'); ?>

        </div>

<?php get_sidebar(); ?>

<?php get_footer(); ?>

Thanks for your help
