KINDLY HELP: PCC QUERY

Hello Friends,
.
I’m going to appear for PCC November 2011 exams both groups. I’m just too much confused with the books. My mind keeps changing which one to start with. I want book for self study purpose. I am not taking coaching for any subject.
.
1) Advanced Accounting and Audit – confused regarding standards only
 .
2) Law, Ethics and Communication – Confused between Munish Bhandari, MP Vijay Kumar and Padhuka (suggest which is good keeping in mind self study, lucid language, conceptual clarity)
.
3) Taxation – VK Singhania/TN Manoharan (thinking of buying Manoharan with Singhania practical book, newly launched)
.
4) Cost and FM – Padhuka/Tulsiyan
.
and if i buy all the books during this month (May 2011), will they contain all the updates applicable for November 2011 Exams or i have to purchase some of them again.
.
Kindly give me your valuable suggestions.
