Repositioning nav bar & adding graphics to theme CSS

I want to make our blog (twenty-ten theme, right now) to look exactly like our website: http://www.jot.org/the blog is at http://www.jot.org/Blogpress.

I’d like to reposition the nav bar to be ABOVE the header graphic and I’d like the nav bar background to be a graphic instead of a plain color. I’d also like to install a graphic that will run down the right side of the entire blog.

I’ve been playing and playing with the CSS code and making minimal progress. I need to go live by Oct 15th so ANY and ALL help would be GREATLY appreciated-PLEASE!
