A couple of off-hand reactions:
- make your action points for conversions more prominent. I come to your site and I'm not sure what I'm supposed to do unless I read and all I want to do is scan. It takes me a while to find the program schedules and sign up info, and figure out that there's an online store. You could for example place a button that stands out that says 'sign up today'
- place contact info on all pages. I would place the contact info on the footer or at the bottom of the left nav so it appears on all pages - it's predictable, gives you credibility and makes it less frustrating for users who are trying to figure out if this business is relevant to them or who are trying to get in touch with you.

Cheers.
