Add to your stylesheet
Code:
#navColumnTwo {padding-left: 0; padding-right: 0;}
#navColumnTwoWrapper {margin: -80px 0 0 0; padding: 5px 20px 0 30px; background: #eeeeee;}
Ideally, find the existing rules for these elements and adjust them as shown. You may need to tweak the paddings to match your current layout exactly.
