What Jonsker said. You need a current medical and a flight review. I am currently doing a flight review and refresher training for a pilot who has not flown for the same length of time. It is surprising how well he is remembering. You can start the FR prior to getting the medical.
Edit: You should also download and fill out
Form 61-9TX This will get you your new pilots licence ready for the flight review to be entered into!
