I bought the books well before I was going to learn to fly, read through them all a couple of times, went to the US and did my exams including RT there.
Although you do not do "over head" joins in the US, its advaisable that you do do an overhead of sorts for uncontrolled (radio) airfields. Over fly the airport 1000' above circuit height or higher, dead side to 'live side', once clear of the circuit decend to circuit height, then turn and join on the 45° for downwind. Works pretty well. There is also no reason you should not practice the standard overhead during your training...
