I can also recommend Stuart McRoberts book Beyond Brawn, very thorough and deep guide to weight training. It has helped me tremendously.
Like many others have replied, focus on core movements and do some reading about macro's - keep your calorie intake above your BMR if you're looking into gaining weight. This is paramount on workout days. Stay around maintenance on non-workout days, and keep protein intake high. A casein shake before you go to bed will ensure that you have a steady supply of amino acids in your bloodstream during sleep. 30g is enough, as the body breaks down 6-8g of casein/h.
Have patience.
