Editing the Admin category page labels

I’ve customised the labels for ‘posts’ using:

//Renaming admin labels
function edit_admin_menus() {
global $menu;
global $submenu;

$menu[5][0] = ‘Project Items’; // Change Posts to Projects
$submenu[‘edit.php’][5][0] = ‘All Project Items’;
$submenu[‘edit.php’][10][0] = ‘Add an Item’;
$submenu[‘edit.php’][15][0] = ‘Projects’; // Rename categories to Projects
}
add_action( ‘admin_menu’, ‘edit_admin_menus’ );

But on the admin page for what was adding/removing categories (now ‘Projects’) still has labels saying ‘Add new category’. Is there a way of editing this text? (and other text like the help on the page)

Thanks
