You may change slug / permalink when editing a post. You can find it below post title which can be edited

you may just try this

<div id="pagemenu">
<?php wp_list_pages(); ?>
</div>

You may use the similar template to index.php and Change Reading settings to show blog post on blog page.

You may need to use members-only plugin and protect pages for members.

You may use

<?
if(is_page('blog'))
get_sidebar();
?>

instead of
<?php get_sidebar(); ?>
in page.php

Hi Swu,

Are you using template page for home page?
