help with modifying css

Good morning

Have a theme on my website http://www.grantharrisphotography.com which I want to make a couple of small mods to but have no idea what to change.
On the home page there are some areas at the bottom, one has my name and address in it and the other says about us.
I want to lose the ‘About Us’ graphic and move both areas of text up so that they are just below the line.

I have spent hours looking through the CSS code to no avail, can anyone help?

below is the homepage template
