Using "Store" as Static Front Page & display store as a matrix, rather than ascending

(Refers to development, using SimpleMarket theme and MarketPress plugin) Our goal is to show the latest products right when a visitor gets to the site – so, would it be possible to accomplish this by using the Store page as the static front page?

Just as important, is there a way to display a matrix of thumbnails, rather than either an ascending or descending list of products?
