[SOLVED] Sizing a new widget area

I've tried to adjust the 'width_x' parameter but I can't seem to get the cells of the widget area to be anything except equally divided in the available space. Also, there is no space between them. They need some kind of padding or margin?? Not sure where to put that.

Here is the URL: http://www.horsemansarts.com

The widget area in question has been put at the bottom of the home page. Any help is appreciated!!

Also, the formatting is different from the widgets in the side bar. I tried removing the before/after html but that didn't change anything. Any other thoughts? Is there a way to format these areas directly?
