Hello NewKid,
I suggest you start by having a look at the Air Law. It is usually the first subject you will have to take. Next is Human Performance (if you still have some time).
Regarding the Kneeboard I think the best would be to wait to be in the states there will probably be a pilot shop not too far .
You will find different kinds and cheaper. First time I went to the US I bought the ASA one which has three sections. Its big enough to hold a couple of charts, the plog and there is a slot for pens, CRP...
Hope this will help.
Where are you going?
Cheers
Al
