Just to back up what FFF and the others have said.
I made the mistake of buying useless Equipment that I don't need.
*A5 Kneeboard when I prefer an A4. (for example)
I would only advise you buy:
Thom Book 1 - Flying Training
Thom Book 2 - Airlaw + Met
You won't need anything else until after first solo anyway.
Good luck
P.S. I found the Pratt books had far better explanations of the content, but the Thom books were far more in depth (TECHNICAL one being far more extensive).
