Tax preparation question?

I'm going to get my taxes done for free at H & R Block tomorrow. I am a college student and both me and my husband work. So I know I'll need to take both of our W2's and my tuition statements to the office. Is there anything else that they'll need? (Like maybe my receipt for books I had to buy or any medical bills/Optometrist/Dentist/ etc. Ive paid?)
