If you have a little command in English then you can skip Wren & Martin and directly start with Word power made easy by Norman Lewis and then can proceed with Verbal ability and reading comprehension for CAT by Nishit Sinha. In the same time you can take help from Time material.

For LR and DI: As you have lots of time hence i would suggest you to start with basic questions like circular =, seating arrangements from any book or any material. You can refer to Logical reasoning and data interpretation books by Arun Sharma.

If you are clear with the basics then you can directly switch to Quantitative aptitude for CAT by Arun Sharma

All the best!!
