Hey

To prepare for MH CET Law entrance, You can use an all inclusive guide like Universal's guide to LLB and CLAT which includes basics and practice questions for all the topics. You can also use the Arihant's guide for MHT CET Law.

Other than that you can refer to previous year question papers for each entrance for a better guidance. For current affairs and verbal section the Hindu is considered as the best newspaper. You can use Word power made easy- Norman lewis for vocabulary. You can use R.S aggarwal'a books for Logical Reasoning or quantitative section in case you need a separate book other than universal's guide.  

Make sure you practice a lot using previous years question papers for a better rank.

Best of luck!
