There is just plain too much information. If you want customers to buy your products they should be able to concentrate on your products. Fewer images - and that's coming from a graphic artist! - and less "noise." Keep product information and images together on a page, information and "interest" stuff on separate pages.
By breaking your content out onto different pages you gain the additional benefit of being able to have more specific pages which will help with
SEO.
