1.) Change header from orange to plain white.
2.) Change footer from brown to white while leaving the footer menu bars as brown and text as orange.
3.) Make posts show excerpts instead of full post on homepage.
4.) Change top menu bar to something more modern so menu item buttons look better.
5.) Make bar white and slightly wider so adsense ads fit properly. (the side bar should still be obvious though).
6.) Remove wordpress bar without the use of a plugin, I use a plugin to do this at them moment.
7.) Create a logo.
8.) Add logo to site.
Plus new menu system
