Question on Catch Box capabilities

I'm looking at migrating my website to a new server and using a theme and had a few questions on Catch Box before I commit to buying the Pro version. 1) Can I remove the huge space above the header graphic? 2) Can I adjust the size (width) of the main body section and sidebars? 3) Can I change the background color of the menu bar? 4) Can you change the background color of the top header part of the sidebar widgets (i.e. change the background color of the Recent Posts section but not the content below it.) 5) Can I tightly couple the header graphic so it extends from end to end and right on top of the menu bar, for what I mean see my current site (http://vsphere-land.com). You can look at my new site http://ericsiebert.com to see how the big space below the header graphic and how it doesn't extend to the very beginning and ends from side to side. Thanks!
