The Rebel, I'm totally with you with regard to a total aversion to all things religious. A good Buddhist teacher will tell you to only believe that which you have experienced personally. Don't beleive anything anyone else says is true. That feels like a safe approach to any spiritual leanings we may have.
I like your version of The Four Noble Truths. I read a book entitled, The Four Agreements years ago. It's not Buddhist Psychology specifically, but dovetails with it well. One of the "Agreements" is: "Don't take anything personally." It's easier to do without a rigid, fixed sense of self. The book may be of interest to you.

PS for onlookers-- My favorite book on Buddhist Psychology is The Wise Heart by Jack Kornfield.
