hi, i would like some advice on how to implement the following features:

- My site is displaying a catalog of products that fall under some categories
- I want to provide some king of 'product manage tool' to be able to add new products (basically a product description, title and a picture) under a given category
- Those products will then appear on my site (usually paginated if there are more than,let's say, 5 products per page) and also a navigation tree showing the different categories should be provided

I would appreciate any kind of advice or approach in order to implement this under Concrete5. Thanks!
