332797 Wordpress theme modification

This should be a fairly easy task for a wordpress programmer. I just installed wordpress 2.8 an bought a theme. Now i would like to change the header/footer so it looks like the rest of my site. My new blog : [login to view URL] Rest of my site : [login to view URL] I also need to add last articles in the sidebar and the author avatar and profile. See picture attached of the final result i expect. As i said, fairly easy. MSN communication and excellent english required.
