Okay, an update:

I know I can style the Product Listing pages by modifying the product_listing.php file in includes/modules/MY_TEMPLATE/ . So I figure I can style that the right way, then plug it into my main page (& the product listing page for the women's category).

So that helps. I'm looking at it now to try and figure out what the PHP script contained within is doing (& how to modify it to only show all the images from a particluar category, minus the "Displaying 1 to 10 (of 19 products)"-type text up at the top & throughout the grid.

So what I basically need to figure out is the code that will call the product_listing.php file's contents and put them onto my main page.
