Combining Product and Category listings

Hello.
On my site I have some products that lend themselves to making variants (size, color) but others that fall under a main category, but are separate products (EBooks about separation anxiety or barking).

Here is my problem.

I want 3 images to show in the "Products for Sale" module found near the bottom of the page: watchandtrain.fatcow.com/YourShop/

The images are correct on the top portion of the module: Training Clickers, Harnesses, EBooks. -- the 3 blank images of the books will go away once I figure this out -- you can click on them if you wish to see that they are separate products.

However, when someone selects EBooks, I don't want them to go to a page with variants (as it functions now -- I made additional separate products after I thought that was a better solution) but instead go to a general Category page with a description of the EBooks and then list the 3 books below that in 3 separate paragraphs with an "Add to Cart" button for each.

So, the Clickers are a single product, the Harnesses use variants, EBooks are a category with description and 3 product listing.

I am sure you can do this, I just can't figure it out.

Any help would be appreciated.

Thanks, that saves me trial and error time.
