Own page design at top of the page and no images on Testimonials

Hello, I am just wondering if it possible to change the order of the front page so that my own things like my E-commerce products can appear at the top of the site under the header? My site is www.totsoffun.org.uk I would also like to know how I get an image to appear above the Testimonials as the Demo shows? Many thanks in advance for the help. Lottie
