Hide Right (secondary) sidebar on certain pages

I got some help on this from makapa in another thread. I made the following entry to my functions.php file:

add_filter( 'sidebars_widgets', 'oxygen_disable_sidebar_right' );

function oxygen_disable_sidebar_right( $sidebars_widgets ) {

	global $wp_query;

	    if ( is_page_template( 'ModifiedBookmarks.php') ) {
		   	$sidebars_widgets['secondary'] = false;
	    }

	return $sidebars_widgets;
}

	add_action( 'sidebar_widgets', 'oxygen_disable_sidebar_right', 11 );

That got rid of the sidebar. To get my content to flow to the right, I then looked inside of that same template and found the content div ID of the material in question. I renamed <div id=”content”> to my own name <div id=”2CL-content”> (for two columns with sidebar on left; I wanted to make the name specific and unique but not to complex). Following that, I was able to add the code below to my style.css:

/* #2CL-content: For allowing text to flow to the right of the page on pages where there
are only two columns with the sidebar on the left.*/

#2CL-content {
	float: left;
	width: 100%;
	margin: 0 0 30px;
}

I have begun adding notes to my modifications along the way so its easier to keep track of my work. When I am done or feel more comfortable, I can then take out those notes if necessary.

Thanks to all who posted on other threads and helped me solve this.
