Some good advice here. Counting calories can be very effective and for many the only way we can learn how much is enough. I would suggest something myfitnessspal.com. I used it for ~6 months but probably could have stopped after a couple of months. It has a really good database of food and is easy to use. I would be careful of all that fat. Not that it is bad for you but it might be more difficult to calorie track.
There is no "perfect" macro distribution. Whatever makes you feel good is perfect for you. Our bodies are very adaptive but like any organism prefers things to be stable.
Some of you may die, but that is a risk I'm willing to take.
