For your current level of conditioning, there is scant need to concern yourself with the amount of protein that you are consuming, unless your diet is particularly restrictive. Most people in the industrialised world consume far more protein than they require, and the figures thrown around in body-building circles are greatly exaggerated and contrary to the science. If you eat excessively, you will put on mass, but it will be fat mass. Fat is not contractile and in no way contributes to your strength, or to the size you are no doubt seeking.
Guidelines from the national institutes of sport around the world are surprisingly consistent, with guidelines for protein consumption for "bodybuilding" generally given as around 1.5-1.7 grams per kilogram of body mass (or 0.7-0.8 grams per pound). Slight excess beyond that point will do you no harm, but it is only going to contribute to your total energy consumption.
As for your energy consumption, many tables and formulae can be found. The Katch-McArdle formula is one particularly good one, since it accounts for the fact that energy requirement is based primarily on physical size and lean mass. (There are numerous web sites that provide calculators for this.) Although it has been demonstrated that we can still gain muscle mass on a restrictive diet, such gain is certainly less than ideal. Therefore, it is important that you try to achieve the minimum multiplied by some factor—typically around 1.4-1.5 times your predicted Basal Metabolic Rate for an active (training) individual—so as not to limit your gain.
As a final note, keep in mind that you require carbohydrates to get maximum gain, since glucogen (muscle and liver stores of sugar) is required for you to lift at your potential, and insulin is anabolic.
Good luck.
