Configuring "Related Products"

I'm going to be selling cabinet hardware on my site. I want to be able to group “families” of matching cabinet pulls and knobs so that when a customer selects a pull and goes to the product page, the other knobs that belong to the same collection will appear.

I would also like to be able to customize the heading of this display to: “Other pulls in this collection” or similar.

I've been through the “edit product” screen and all it's tabs about a dozen times, but I can seem to figure out how to do this.

Any help appreciated!
