“you are here” in header

I’ve been trying to figure out how to create a sort of “you are here” thing in my header, but I can’t figure out how to turn the title and post names into links.

I’m using the title tags:

<div id="headersitemap">
<?php bloginfo('name'); ?>
<?php wp_title(); ?>
</div>

Any suggestions about how to turn those into links?

Also, can anyone make a guess as to how I would put the month and year inbetween the homepage and the post title?
