My advice would be the following:
1) Get more dives. Real life diving usually is a bit different from training dives. I experienced it by myself when I dived in liveaboard in Red Sea (diving conditions there much tougher comparing to my training dives in Thailand or Philippines).
Make your own research about diving centers in Puerto Vallarta. Look at tripadvisor, facebook reviews. Try to understand which dive centers provide good service. Then dive, dive and dive.
2) Think about your learning path as a diver. What courses are interesting to you. With which agency you are going to be associated, what are your plans for diving (wrecks, corals, deep dives, muck diving, cavern - cave, ice diving, etc.
