I also got that book on Ldahl's recommendation and I agree, it is excellent. I am reading through it for the second time. I like the way he lays out the pros and cons of the different ways, thinks of things I had not, like creating an annuity for when you are over 80, the longevity insurance thing.
My favorite book on this subject is Wes Moss's You Can Retire Earlier Than You Think. Between the two books, I am fashioning our early retirement plans--I am semi-retired from my full-time job, work part time and take social security. DH still working.
Both books have so much to offer. I have not found a financial advisor and just trust them.
Wes Moss did lots of statistical work and has guiding principles of what the happiest retirees have in common, much like Razz's list. Here is an article he wrote that summarizes what he found:

The Vernon book is great for the actual planning of incomes streams. The Moss book is better for me for an overview of leading up to full retirement, of figuring out how to be happy and secure before undertaking retirement, since that is his focus--what separates happy retirees from unhappy ones.
