Post Type

Hi
I used the below code to make a custom post type

if ( ! function_exists( 'post_type_entry' ) ) :

function post_type_entry() {

	register_post_type(
		'entry',
		array(
			'label' => __('Entry Pages'),
			'description' => __('Create an Entry Page.'),
			'public' => true,
			'show_ui' => true,
			'has_archive' => true,
			'capability_type' => 'post',
			'rewrite' => array(
  			'slug' => 'pages' // This controls the base slug that will display before each term
  		),
			'supports' => array (
				'title',
				'editor',
				'thumbnail',
				'excerpt',
				'custom-fields',
				'revisions',
                                'page-attributes'
			)
		)
	);
}
endif;

add_action('init', 'post_type_entry');
add_theme_support( 'post-thumbnails', array( 'post','entry' ) );

I would like for the user to be able to choose the parent page and the template like they can on pages. How do I do that?
