Easy Populate Product Set Up Confusion

I am new to easy populate and am confused about inital setup. I am selling perfume. I notice many sites have the product brand, picture and description then underneath the attributes (sizes, style with model numbers). How is this accomplished? Everytime I try to set up intial product, it shows up I have to put in some kind of quanitity which i set to 0 then says out of stock. I do not want the intial description to show quantity or size, I want that to be in the attributes.. Would I have to set inital product up like (Giorgio Beverly Hills Size 1.7 oz) then add attributes from there. I just really wanted it to say Giorgio Beverly Hills then have the 1.7 oz as attribute 2.5 oz, ect., but how would I set product up initially if easypopulate dont work without a model number?

Hope someone can shed some light on this.

Also, I have posted this before, but never received an answer. I have added msrp field to easy populate. The download complete file txt came out fine, showed the msrp field, however, when I downloaded the model/attributes txt the mrsp field did not appear. Does anyone know how I can fix this?

Thanks you guys for taking time to answer my piddly questions.
