I would say look at the Sticky called "how to bulk" that will give you a good base.

Now here is the tricky part. Unless your a very inexsperienced beginer, then losing fat and gaining muslce at the same time can be impossible. Which is what your describing. My advice would be to eat big and bulk up. You dont need to go crazy, but if you want to grow you have to eat.

You can always cut later.
