Most important! Do all the various codes you have found actually work with the devices you have? Individually, not all together as you are planning to do.

I would suggest you test each piece of code with all the hardware connected. Be sure all the grounds are connected. Then get one of the arduino cook books, it will help you understand what you are trying to do. This is not a weekend project. Try this link: Arduino programming for beginners
This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!
