Muscle Gaining. Where do I start?

Okay so I'm 16, 130 lbs, 5'9, skinny as hell, and I want to gain some muscle. I am pretty fit, I can run a mile just under 7 minutes, but I want some upperbody strength. I want to know how to get a good build. I need to know what muscles I should focus on, and what can I do around the house? I can't go to the gym to work out because I'm in the process of getting a house, (July 27th is when we close on it) and I don't live near one atm. I've googled a bit and found a regimen of 200 pushups a day, spaced out. 40x5 on odd days, and 20x10 on even days. Do protein shakes, bars, etc. make a difference? I am 110% willing to do the work.
