Editing 'List of Posts' Template to show only one category.

Hello! I’m very new to this and am just learning code. I’ve recently figured out how to allow any page I wish to show posts set to a specific category ID using the following code before the loop:

<?php
$catID = 0;
if (is_page('me')) {
  $catID=11;
} elseif (is_page('poetry')) {
  $catID=2;
}

if ($catID) {
   $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
   query_posts("cat=$catID&paged=$paged");
} ?>
<?php
		if ( have_posts( ) ) {

			while ( have_posts( ) ) {

I would like to know if it would be possible to make the following template which currently shows ALL posts ever made when it’s in use to do the same thing but I’m not finding where to edit or what to change. with pages the loop was easy enough to find from other information I was able to see on this support site but this looks completely different to me.

The code for that template is here:

<?php
/*
Template Name: list of post
*/
/* Customize options
$raindrops_list_of_posts_per_page	= 10;
$raindrops_list_of_posts_length		= 200;
$raindrops_list_of_posts_more		= '[...]';
$raindrops_list_of_posts_use_toggle	= true;
*/

if ( ! defined( 'ABSPATH' ) ) { exit; }
$raindrops_current_column = raindrops_show_one_column( );

if ( $raindrops_current_column !== false ) {

	add_filter( "raindrops_theme_settings__raindrops_indv_css", "raindrops_color_type_custom" );
}
get_header( $raindrops_document_type );
do_action( 'raindrops_pre_'.basename( __FILE__) );
raindrops_debug_navitation( __FILE__ );

			raindrops_prepend_extra_sidebar( );

			get_sidebar( 'extra' );

			raindrops_append_extra_sidebar( );

<?php
		} elseif ( $rsidebar_show && false == $raindrops_current_column ) {
?>
			<div class="yui-u">
<?php
			raindrops_prepend_extra_sidebar( );

			get_sidebar( 'extra' );

			raindrops_append_extra_sidebar( );
?>
					</div>
<?php
		} // end if ( 3 == raindrops_show_one_column( ) )
?>
				</div>
			</div>
		</div>
<?php
		if ( raindrops_show_one_column( ) !== '1' || false == $raindrops_current_column ) {
?>
		<div class="yui-b">

<?php
		} //end if ( raindrops_show_one_column( ) !== '1' || false == $raindrops_current_column )
?>
	</div>
<?php get_footer( $raindrops_document_type ); ?>

I know this is likely to be rookie info but I’m at a loss and would appreciate whatever information or input you can provide.

Thank you for your time.
