Page order

I’m having trouble with the order of pages on my website. I do not want the pages to go in alphabetical order, but I don’t know how to change it. I think I have WP 2.0? In my theme editor, I have this which is where I think I need to change something, but I’m not sure what exactly.
Could someone help??
Thanks!

<!– This is the menu of pages–>
<div id=”menu_view”>

• “>Home

<?php wp_list_pages(‘depth=1&title_li=’); ?>

</div>

<!– this displays the subpages – if any – in that red menu–>
<div id=”sub_page_menu”>
<?php if(wp_list_pages(“child_of=”.$post->ID.”&echo=0″)) { ?>

<?php wp_list_pages(“title_li=&child_of=”.$post->ID.”&sort_column=menu_order&show_date=modified&date_format=$date_format”);?>

<?php } ?>
</div>

<h1 id=”header”>“><?php bloginfo(‘name’); ?></h1>
