I constantly lift, and I can tell you that Dips focus on Triceps. What I would say is do alot of wide arm push ups. If you tore your pectoral I say: DO NOT USE WEIGHTS! Weights tear your muscles slightly, and your pectoral may not be ready for that yet. Pushups, on the other hand, only use your own body weight (obviously) ad do not tear your muscles.
Review: Do pushups to tone your pecs back to how they used to be. Only after you're positive the pec is back to normal, should you use weights (Benching, Flys, etc)
