WordPress product catalog site [closed]

I need to create an e-commerce site with WordPress, but not 100% e-commerce. It is just a catalog site without shopping cart. Users can see various products on the site, for example, car showcase website.
I am a newbee to WordPress. To build such kind of site:

• What is a good start point to study?
• What plugins do I need to install?
• Do I need to install wp-ecommerce plugin?

I appreciate for any help and suggestions.

• What is a good start point to study? Read a few tutorials on Custom Post Types and Custom Taxonomies. Here´s a good one to get started.
• What plugins do I need to install? It wouldn´t be too difficult to create the site structure without any plugins.
• Do I need to install wp-ecommerce plugin? Based on the information provided I don´t think you need that.
