Questions about turning my wordpress site into an ecommerce site. Experience needed.

[PEnterprises]

I have a wordpress site that is about a product that is now getting some great traffic. Right now It has affiliate stuff on it. I want to sell my own product so I will be turning this wordpress site into an ecommerce site.

I want to redesign it so I am not looking for simple plugins to just add a cart.

The part I am really confused about is what to do with my posts and categories? How does that work when turning this site into an ecommerce site?

Lets say the site is "hats for adults" My post pages are things like "funny hats for adults", "hats for adult men" etc etc. Would I turn these posts pages into like category pages that have a category of products.

Or should I create real categories and have my developer turn those into the ecommerce category pages and then redirect my posts to those categories?

Maybe I don't even know what I am talking about. Is this even making sense? This is a small site (5posts and 1 category) and most of the traffic will come from the homepage keywords anyways.

I would use the current posts as the blog area of the eCommerce website, I would then create new cats for the products you actually want to push.

If you find one of your posts is relevant to a product I would then create an anchor text link back to the product, I would even keep that blog section running with the posts and keep linking out to products when relevant.
