Try editing the stylesheet since i am not sure which one is causing the gap application or product tags. You have to do on trail and error basis.
stylesheet.css would be a good start

Do you have a link to show us? Its hard to tell without seeing what sort of classes/stylesheet changes you have. The default template doesn't appear to have anything that causes a large space, so I'm assuming you have some sort of custom or modified template.
