Reposition Menu Bar & External Forum Link

Hi,

I've adjusted header.php as instructed in another forum to allow external links (to my static pages). I have 2 questions:

1) How do I reposition the menu bar at the top of the page as it was in your original theme?
2) In the external links section of header.php, I included an external link for "forums", assuming that I would then include an external link leading back to my WordPress/Simple:Forum link. Should I have kept this one menu item non-external? How do I fix this?

Here's my URL: http://photogeist.com/social/

Thanks!
