Help moving content/header/nav down?…

Hey everyone!

My website at: http://www.vibemusicmix.com is working great, but I would like to move down the rest of the page/make the header area bigger, so I could fit the logo in the header section

Here is the Style.css code:
[large amount of CSS code moderated – a link to your site is enough to access the styles; please review http://codex.wordpress.org/Forum_Welcome#Posting_Code ]

Can somebody re-post the code, or highlight where I would need to change the items.

You can get an idea of what I want to do at my site: http://www.vibemusicmix.com

Thanks,
Adam
