Dear student,
aspiring for JEE 2016 well in advance seems a good way to go. As you have ample time on your hand, you should be steady in your approach for the exam preparation.
As far as the books are concerned, you can go with any previous year question paper booklet and a question bank. Most of the students don’t follow a single question book till the end and switch to another soon before completing one. Follow a reference book when needed. You can switch to different reference books from time to time as you may need but then after completing the topic, switch back to your textbook that you have been following . This approach helps you cover all the topics without leaving any which is possible if you follow different books at a time.
Also, join a test series to help you evaluate your preparation. May the force be with you.

All the best
