Featured Products add to cart and description

Hello,
I am having few problems with my testing site, i wanna make my featured products in the main page, all display the price clearly, a button to "add to cart" and small description of that item, anyone knows the file(s) responsible for these features? or anyone who did stuff like that can help me ? i am trying to make it easy on customers when they see a featured product and like the price and the description to be able to directly add it to cart and buy it.
Thanks a lot
