In my opinion, the 37signals style of displaying a product works so well is because of amount of information readily available with such little effort. Your design looks pretty attractive already and is in a similar sales letter type layout - consider adding a tour with large screenshots. It may also benefit you to mimic the style of their pricing page with each plan laid out, even if the primary one is free. There's a sense of mental relief if the customer knows what he/she is getting into at a quick glance and that pricing chart helps a ton in providing that.
