Graphicriver template: a PDF ebook and embedding it

Hi everyone,
I’m new to this stuff so I need some help. I would like to buy a template with help of which I’ll be able to put together an ebook. While browsing GraphiRiver I came across 2 categories:
What’s the difference between the files that I get?

For now, I would like to buy a template that will allow me to create my ebook, that people will be able to download.

In the future I would like eventually to have an embedded magazine on my site the way they did in ie when someone clicks there on the edit it shows them an online magazine with active links to the products on their site. What kind of plugin will I need to get to make this happen. I’m using Wordpress with WooCommerce but might switch to Magento in the near future.

Thanks for your help.
