WordPress SEO Modify Title Pages

According to the WP SEO instructions, I should change the Title Section of my Header.php file to the following:
<title><?php wp_title(”); ?></title>

This (I think) is the complete Title Section of my Header.php file using a WP Weaver theme

<title><?php
if (weaver_getopt(‘ttw_hide_metainfo’)) {
wp_title(”); /* this is compatible with SEO plugins */
} else {
/*
* Print the <title> tag based on what is being viewed.
*/
global $page, $paged;

wp_title( ‘|’, true, ‘right’ );

/* Add the blog name. */
bloginfo( ‘name’ );

/* Add the blog description for the home/front page. */
$site_description = get_bloginfo( ‘description’, ‘display’ );
if ( $site_description && ( is_home() || is_front_page() ) )
echo ” | $site_description”;

/* Add a page number if necessary: */
if ( $paged >= 2 || $page >= 2 )
echo ‘ | ‘ . sprintf( __( ‘Page %s’, WEAVER_TRANS ), max( $paged, $page ) );
}
?></title>

What exactly do I need to do to make this change correctly?
I guess I can use the opt-out strategy and Force rewrites, but WP SEO says the other way is better.
Thanks
