Header and Menu Bar

Hi there, I'm wondering if it's possible to move the menu bar items so that they show level, beside my header (to the right) rather than underneath it, and then to make the whole header the same colour/texture of the menu bar with it stretched across the whole page. (Basically like the catchthemes header is right now) My goal is to narrow the branding area so that is creates more room for homepage content on my screen. http://www.strangeisland.com/ Thanks, Kevan
