Megs and the others gave you good food advice I am weighing in with some exercise advice. Don't go crazy and all out the first week. Start moderately easily and build. It's really easy to jump in with both feet and find yourself burned out two months later. Go at a pace and difficulty level you can sustain without getting injured or overwhelmed and change your activities every 6 weeks or so to prevent boredom.
I include free weights, walking, elliptical, water aerobics, golf, swimming, pilates, and an occasional massage in my fitness routine. Not all every week and using different routines and intensities to change things up. If I did the same thing every week I would go nuts. I also take a full day off each week and a full week off every 12-13 weeks. My way may not be right for you but it is something to think about when you plan your weight loss strategy for the long haul.
