I have various categories of products that I need to list on their own pages.
For example: I have a bunch of t-shirts that I want listed on a T-Shirts page/category.
How do I accomplish this?
Do I first create a page or a category then create each product and assign each product to that T-Shirts category?

When someone clicks on T-Shirts, I want a list to appear with thumbnails of each product.
When someone clicks on a thumbnail or name, I want a larger image to appear with that products description, larger image, etc.

Thank you, in advance, for your assistance.
