to remove the post/page title you can use the title="false" parameter, but I guess this is a hardcoded title. In posts you can add custom text as an excerpt, but pages do not have excerpts. However, there's a way to add excerpts to pages in WP2.9:
add_action( 'admin_menu', 'bf_excerpt_meta_box' );
function bf_excerpt_meta_box() {
add_meta_box( 'postexcerpt', __('Excerpt'), 'post_excerpt_meta_box', 'page', 'normal', 'core' );
}
This will be a part of the theme from the next version, but to add this to the current version it's just to add the above code to the functions.php file.
