At first glance, the site looks great, as do your products. One thing I noticed is that the product pages (e.g.
here) display the image above any text. Scrolling is always an issue for inexperienced web users, and it may be worth changing the product page template to combat this (With the title, breadcrumbs, and a note to say "scroll down for purchase information" above the image).
Also, if you're planning to market through the search engines, Nikki's site is a great resource
