What can I do to prepare to get pregnant?

My husband and I are going to start trying to have a baby spring of next year. I fully plan on discussing everything with my doctor but what are some of the things you have done to prepare your body for pregnancy? How soon before trying to get pregnant did you start taking prenatal vitamins? Were they the ones over the counter or by prescription? I already cut my nightly glass of red wine out of my diet. I'm only going to drink wine on special occasions during the next year and obviously stop once I get closer to getting pregnant. I want to try to have the healthiest year I can to prepare my body. Is there anything else I can do besides eating healthy and exercising?
