Buddypress + Light shop plugin customization

I have a site that I am close to completing. I am using the elegant themes "Nova" theme. I have the Shopp ecommerce plugin installed and need some customization to get it to look the way that I want. Firstly, I was able to edit the css to add a border around the inventory in list view, but not in category view or product detail view.. I need that done to fix the look. The website is a bicycle repair company and parts and accessory sales. I want to have a complete catalog at this point without having to stock all the items(too costly). I want to change the shop template so when items are out of stock they can be submitted for a quote. I can then order them from my distributor and deliver them or ship them after i receive the items. The reason for this is that I can still sell and ship the items I have in stock to anyone, but local clients can see what I am capable of getting for them and place a special order. Just like they would if they walked in to their local bicycle shop. BuddyPress I want to integrate buddypress with my current theme. Since I have put so much time in to putting together my site structure on my current theme I don't want to have to change it again. I have installed buddypress and I have installed the other plugin that is supposed to integrate my current theme with it. It looks like hell. My goal with buddypress is to create a forum and let people make some connections.
