coller theme: moving the widget area

Hi,

I’m using the coller theme and trying to customize it using CSS. So far I’ve been successful in changing the size of the slider box and moving it to the right. Now I just want to move the widget area up to just underneath the navigation bar and right beside the slider box.

Here’s my site: http://www.chocolateandconnie.com/

Does anyone have any suggestions for going about this?

Warmest thanks!
