Ok, so right now I'm in the process of figuring out my daily calories. However, I could'nt find how many calories I need to gain weight

. I know how many I need to maintain, but how about gaining weight? Should i go with what Lou said about adding "5 to 10 calories per pound"? And I have two other questions:
How many grams of protein should I eat per day? 1 pound per BW?
How many grams of carbs? I figured I'd substract the total of protein and fat calories, and the rest should come from carbs. Am I right here?
