I assume that your quant's score is better than that of verbal, so I think here is a possible plan...
Books:
For SC:
MGMAT SC is the key to success. Read theory, do the problems at the end of each chapter and return to the theory if you get wrong. Practice makes perfect. SC is pattern; the more you do, the more you will be proficient so that you can spare time for CR and RC.
Other good material are SC Grail and our forum's resource : gmat-grammar-ultimate-by-gmat-club-102387.html
For CR: I choose CR bible. The structure of the book is clear and its explanation helps me a lot.
RC: Reading, reading, reading.... I prefer magazines to fiction because it's up to date and I think that their contexts are similar to those of GMAT. However, you may prefer fiction :D. Your choice. Try to get the main idea, the tone and the structure while reading.
