As posted before, ask your instructor, he/she will tell you and has a much better awareness of your personal needs as a student and the precise circumstances of your (planned) flight training than anyone here.
Having said that, if you find the time (money not so much an issue in this case), you may consider downloading the
FAA Airplane Flying Handbook (42 MB) and the
FAA Handbook of Aeronautical knowledge (109 MB, both free) and getting a copy of "Stick and rudder" by Wolfgang Langewiesche.
Enjoy your flight training, but be prepared to become an addict
