Can I suggest you visit the club you want to learn at, sit down with an instructor and ask him or her to explain the whole process to you.
If they are not prepared to spend some time with a potential new student, who is intending to spend a lot of money with them, then go to another club or school until you find one that will.
Remember you are the customer, and free to choose where you spend your money.
Oh and you do not need to buy all the books etc at the start, all you really
need for the first few hours is a logbook, checklist, the books covering the flying exercises and principles of flight.
