Reducing Margins in Header and Body, Search Box

Hi, Where do I modify the margins for the header and body in Catchbox Free? For example, on this site: http://www.hayatidede.org/wptest/ How do I remove the space before and after "Mevlevi Order of America," and between the Meta Slider and the Featured Posts in the right nav? Yes, I know I would need to do it for the various widths that allow for responsive design - I'm just not happy with the specific margins. What about the curves in the various body "modules"? I'd also like the Search box to sit to the right of menu. Can you help? Thanks, Jason
