Now NCERTs are must have books and apart from that you should use above mentioned books as reference books where you will find different type of questions covering all the concepts in detail and as soon as you would start it would be much beneficial for you because JEE-Main consists of syllabus of class 11th and 12th both so if you start your preparation of JEE-Main from class 11th then it is much better for you.

You can also take JEE-Main Learning package for your preparation
