I`ve been at this stuff for years but never really learned how to actually build a website successfully.
So I`m not completely knowledgeable in this area, .wrap? div? floating the contents? entry header? entry-content? (you really need to sort out that background image on load.)
I have no idea what these are referring to, I was assuming that WP would be a little more user-friendly than back in the day when I was trying to understand HTML
