Everything that's been said so far is pretty good. Understand that nutrition comes first, You have to know what
kind of calories to take in as well as how much and when. Here is a great article to get you started:

Keep in mind that the more research you do, the more you are going to find that the experts all have their own opinion about how much protein, carbs, fats, etc. you should have in your diet. I recommend choosing some guidelines (e.g. 1g of protein for every lb. you want to weigh, or a certain % of protein, carbs and fats) that you can manage, and adjust when you need to once you start seeing results. It might sound like a lot of work, but the payoff is worth it.
