Adding a Logo and Adjusting Padding

Few things: 1. Is there a way to include a logo above the page title and promotional message? 2. Can I edit the size/padding of the transparent box around the Slide Image text? 3. Can I decrease the padding between the Site Title/Promotional Message and the Page Title/Content seen here on page I'm currently trying to adust: http://lexingtonadvisorsinc.com/about/ Thanks for all your feedback, you've been very helpful!
