I'd go to some flight school for some hour or two of dual. Then they can tell you what you need and you become motivated at the same time. If you move on see the medic first to get a new checkout there and then you are good to do the rest. I'd say a school is best to get you up to standards again fastest. I let my PPL get rusty several times and could catch up quick at flight schools every time. Many small things change all the time so it's truly valuable to get updated by pros. And they can fine tune your flying to perfection.
