Pcm sent me home w/ 4pgs if lab results. I'm home now and I don't understand how to interpret them. Does that mean nothing's wrong? Should I call them?

Knowledge = Power. Yes, if you don't feel like you understand your lab results, you should talk with your doctor about them to make sure everything is ok. It's most likely that they are all normal because usually your doctor will and should discuss any concerning abnormalities with you.
