"Gaining pecs" and "losing the spare" seem like vague goals when coupled with "look like everyone else" on the board. If you generally want to get bigger and stronger and look better and fitter all over, you need to work your whole body, not just your pecs.
Buy the 5-3-1 e-book. Its $10-20 IIRC. It will at least give you a place to start and then come back and ask questions. And maybe get "Starting Strength." It is another good resource.
In a nutshell, there are six basic lifts that will help you get stronger and just be a better person overall: Squat, Deadlift, Bench, Overhead Press, Row, and Pullup/Chinup. These are the basics and other lifts are assistance work and optional. I'd suggest a program that focuses on these important lifts (5-3-1 does this) and you can add assistance later or as needed.
Your diet is going to determine whether you have a spare tire. You can't out-exercise a shit diet. So look into diet as well.
