Page set up

I have absolutely no idea where to get started on this one, basically I will be putting books and toys on my site as affiliates. The way it is now is very basic and the pages I make are just that, pages with no breaks etc. As I do not know the correct terminology for what I want *blushes* I thought it best to provide an example…

I would like to have sections as the site does here, except I will just be showing a picture and a brief sentence of two on the product, I was going to add a buy it now image myself and just add the affiliate link to that.

So anywa, this isn’t so much about the affiliating side of things, but how do I go about setting certain pages up as they do on the poster site?

Many thanks if anyone can point me in the right direction 🙂
