Go pro's advice was sound. However, if you need to specialize in calves, training them more than twice a week is ok as long as you use the methods of periodization. My calves were really lacking (and they still are) but i worked them 3 times a week for 4 weeks and they really grew. I incorporated low and high reps for the same workout and the same exercise. I think go pro is good with periodization so i say go to him. As for shoulders, I would say generally, once a week is enough because they are hit while doing chest, and back. However, your case might be different. Are your shoulder lifts progressing each workout? If they are, i would say not to worry about it. But if they are not, i would sit back and re-assess what is going wrong. You can change the number of reps, sets, tempo, rest period, or even the exercises. Good exercises for shoulders are:
Over DB press
Military press
Clean and jerk
Cleans
lateral raises
bent over lateral raises.
