Career in investment banking

Hello members.. I am awaiting my CA Final Nov 2011 results and scheduled to complete my articled training in January,2012. Also, I have completed my graduation this year. I am interested in Investment Banking and would like to adopt it as a career option for me. 

So, I want to know that what role can a Chartered Accountant can play in the field of Investment Banking, what are the oppurtinities available? And also how right is Investment Banking for a Chartered Accountant as a career option.? How to begin with a career in this field?? I would request the members also to give their opinions from time and money point of view.. 

At present, I am 20 and a half years old and also planning to pursue at least CFA and MBA in Finance (will try for it in IIMs) in days ahead. And also, I am pretty excited about adding Company Secretary as a professional qualiication to my profile..So would CS be an advantage if a career in Investment Banking is pursued??

Please provide a detailed in depth guidance on the issue.

Regards
