If your eyes are sensitive to light, you might want some sunglasses; preferably with thin arms and the sort that wrap around. You might prefer to wear gloves; leather golfing gloves or driving gloves are cheaper than the proper flying gloves and serve the same purpose.
Other than that, you instructor will be able to advise as you progress through the course.
You will need study books for the exams and eventually a flight computer, charts, pens, ruler and protractor, a kneeboard and a bag to carry it all in, nothing fancy though; I use an old briefcase.
