Ca final books suggestion required

Kindly give suggestions for CA Final Books regarding following   

1. Financial Reporting - I have taken classes from Parveen Sharma sir in 2014,  Should I use MP Vijaykumar's book along with Practice Manual and Study Material ? or doing Practice Manual and Study Material along with Parveen Sharma sir's notes is enough ?

Practice Manual and Study Material is enough for Accounting Standards ?  

2. Law  - suggest me book only for questions practice other than Practice Manual  

3. Costing - I have taken classes from Sanjay Aggarwal sir.  Should I use Paduka book along with Practice Manual and Study Material ? or doing Practice Manual and Study Material is enough ?  

4. Direct Tax - suggest me book for questions practice other than Practice Manual. Should I use Paduka's Question book or VG sir's Question book ? I think VG sir's book does not cover RTP and it will be available only in Feb 17.
