And don't forget dead lifts and pull ups. I see a lot of people at the gym focusing on chest and upper body (biceps, arms, torso) but you need to focus more on centre of your body and lower back (dead lift), legs (squats, leg press) and upper back (pull ups).
Bench press is also good but that's it for chest, I wouldn't do more. Squats, bench press and dead lift as a core of your routine is a good idea. You can add some other minor components but you should keep focus on the big three.
I'll also add that before embarking on a serious squat regimen one should work first with a trainer (or friend with good technique) to develop proper squat form. Squatting is one of those gym exercises that is often underestimated in its difficulty and is routinely done incorrectly, leading to injury.
