Wordpress admin labeling

Hi

I use this plugin. I believe it addresses what you are looking for.

Dashboard Admin Notes

You can add a Custom Dashboard Widget using 'wp_dashboard_setup' action hook..
Try this in a mu-plugin (you can test this also in your theme's functions.php):

// Adding Custom Dashboard Widgets
add_action('wp_dashboard_setup', 'yourprefix_custom_dashboard_widgets' ); 

/**
 * Adding Custom Dashboard Widgets
 * Callback function of the 'wp_dashboard_setup' action hook.
 * 
 */
function yourprefix_custom_dashboard_widgets() {  
	if ( current_user_can( 'manage_options' ) ) {//new: wp 3.7
		//usage: wp_add_dashboard_widget($widget_id, $widget_name, $callback, $control_callback );
		wp_add_dashboard_widget('yourprefix_your_custom_dashboard_widget_slug', 'Your Widget Title', 'yourprefix_custom_widget_content' ); 
	}
}  

function yourprefix_custom_widget_content() {  
	echo '<ol id="my-dashboard-widget-list">' 
		. '<li>Something to do</li>'
		. '<li>Something else to do</li>'
		. '</ol>';
}

I used this

function custom_help() {

global $post_ID;
$screen = get_current_screen();

if( isset($_GET['post_type']) ) $post_type = $_GET['post_type'];
else $post_type = get_post_type( $post_ID );

if( $post_type == 'business' || $post_type == 'ai1ec_event' ||  $post_type == 'story' ) :

$screen->add_help_tab( array(
'id' => 'business_help_tab', //unique id for the tab
'title' => 'Instructions', //unique visible title for the tab
'content' => '<h3>Images</h3><p>The Featured image JPG must be 1500×515 pixels</p>', //actual help text
)); 

endif;

}

add_action('admin_head', 'custom_help');
