In your full body routine, are you putting chest and shoulders first in your workout? If that's what you want to grow, I would prioritize them. You could also add a second set to say chest on Monday and a second set to shoulders on Friday. Sometimes prioritization, along with extra "work" will stimulate them.
As for adding the calories, it doesn't sound like you track your food, so your are using a more intuitive method to add those 200 calories from protein and fat. I use myfitnesspal app, as at least a guide and when bulking, instead of adding more calories per meal, I add another meal. Just my two cents, I hope you make the gains you are looking for!
