(Suburbia) How do I get the top row to display more posts

Need to edit the Suburbia theme so it displays four posts at the top. Can’t seem to figure it out but I know it must involve the code in the home.php

<?php get_header(); ?>

	<?php include (TEMPLATEPATH . "/sidebar.php"); ?>
    <?php
        if ( $paged == 0 ) {
            $offset1 = 0;
            $offset2 = 2;
        } else {
            $off = $paged - 2;
            $offset1 = $off * 7;
            $offset2 = $off * 7 + 2;
        }
    ?>

Please halp!
