James,
As I have learned from many of the wise ones on this forum for years, take your time and rationally think this through. You are embarking on a journey that, whether you may realize it or not, likely means taking your wall of faith down brick by brick. That is exactly what happend with me, but I cognitively knew that was where I was heading at the beginning of my journey out of the WT. I was in it for decades and served as an elder like you. I would also recommend that you continue your research; I read nearly everything about philosophy and religion upon my exit because I wanted to know how in the world I could have allowed myself to believe the WT and fall under its draconian control for so long.
I also took several religious courses when I returned to college; "In Search of the Historical Jesus" was one of the best courses I have ever had, and it opened my eyes to a more rational, secular view on the topic. After years of meditation and study I came to understand why I allowed myself to come under the WT control. The primary reason is that I was raised with a belief that the Bible was inspired and a belief in the god(s) of the Bible. Secondly I was raised around the WT from a young age. Then came the message of the paradise, the healthy way of living followed by JWs and finally the terrible history of Christendom. Once I realized all of this it was only a matter of time before all of the bricks were gone.
Good luck in your own journey and where it leads you.
