As a first reccomendation, head to
http://www.abcbodybuilding.com and sign up on their forums, they can provide a lot more information than I can.
Second, you'll need to eat, preferably some six 3-350 calorie meals a day, hungry, not, eat. Eat natural foods as much as possible, plenty of veggies, and plenty of healthy protiens such as fish (tuna is your best friend... just get used to life without mayo), chicken, pork, beef (go for lean steaks), nuts (in moderation), dairy products (eggs, plain yogurt cheese, milk). If you dont have the time to cook all of those during the day, getting a good whey protien can help, mixed with milk, and even a tablespoon of pb. Working out regularly is great, but rest is key to growth. Make sure you sleep at least 8 hours a night. When you work out, try to fit a schedule isolating muscle groups, for example: Monday biceps, tuesday calves, wensday upper back, thursday thighs, friday triceps... You get the picture. Start with the heaviest weight you can do an 8 rep set with, and then when you work to failure with that weight, slowly remove the weights 10 lbs at a time untill your down to a moderate weight, and furthermore exaustion. It seems like a long process but actually takes no time at all.
Good luck.
