I'm calorie counter and want to suggest a couple of things. First, you might want to check out the calorie counter community here at 3fc. Second, go on Google and do a search for Resting Metabolic Rate calculator. You will be asked to plug in your weight, height, and I think gender. It will give you an estimate of how many calories your body burns if you stay in bed all day. I would eat that amount. That way, any exercise you add to your program will be creating a major deficit in calories and, thus, lead you to lose weight. Some people eat one or two hundred calories more or less than this number, but you could decide that on your own after you try it out and see how it works for you. By the way, the more muscle mass you have, the more calories you will burn while at rest, so I highly recommend lifting weights too. Sorry if you already know all this, but I just can't help myself!
