Multiple selection boxes and headings for a product

I have a fashion estore using zencart. V 1.3.8 and I have just added Stock by attributes to the store for better stock control due to colours and sizes of my range.

I have 4 main categories in my store

Collection
Basics
Cardigans
Get the Look

I have created a product by look (Get the Look Category) which I want to show as a picture of several products you can buy from the 3 categories and if you buy them all you get a discount and "Get The Look"

My questions are:

I have created a product called Look 1 within the "Get the Look Category" and the associated images but how do I have 6 different attributes for 3 different items and have headings above them to clearly state that select size and colour for the dress, size and colour for the leggings, size and colour for the cardigan.

I can get the 6 attributes into my page but don't know how to add headings so the customer knows that these 2 attributes are for the dress etc.

The pricing is fine because I can cost it as a product price but my other question is linking the stock quantities from the "look" to the original quantities listed in the products under Collection, Basics and Cardigans.

So if I buy Look 1 I want the stock quantities to decrease from e.g Goddess dress, black, size 14, from the Collection Product Name Goddess

Is there a smarter way of doing this?

Thanks!
