Sammy is spot on:
The history of Certified Financial Planners as a profession is a relatively recent career path in terms of processes and certs.
A brief history:

Not really for me but I have a background in econ and finance.
Financial Planning, however, really doesn't require much more that a systems engineering approach to finance: I call it institutionalized common sense.
There are many, many really fine tools to help get you started to form a baseline of understanding so that you can ask the right questions, mainly to yourself and family (you have to work with your family): Risk tolerance, goals, work tolerance after retirement, current financial status, etc.
I never recommend specific stuff beyond books, which Paul has covered.
Spend at least six months getting familiar with the lingo, the never ending alphabet soup of finance and investments.
My nephew is an investment banker in Atlanta with all the certs and quals in the industry. I have to prepare to talk to him since I am not as fluid in finance as I used to be.
I also have a very good friend you does estate and financial planning in Richmond for a really great firm, which he owns.
I don't do business with either (never mix family, friends and money) but they provide me with insight, not recommendations, on trends. Once or twice a year, tops.
Start there. Expand your knowledge and ask your circle who they recommend for initial guidance.
