I stumbled upon your site by accident while looking for something else. I just read the story of your life and have been perusing some other areas of the site.
Your story reads like a laundry list of some of the most misguided doctrines and their proponents...Pentacostalism, AOG, Rushdooney/Reconstructionism, Arminianism, second baptism nonsense, Charsmatic tongues, premillenial eschatology, the list goes on...UGH! Not to mention some of the most pathetic answers and worst advice I've ever heard from clergy or someone who professes a knowledge of and belief in the God of the Bible. Misguided is putting it mildly, some of this stuff is positively delusional.
Without getting into a lengthy discussion, it seems to me that in all of this you never really started at the begining and got answers to some of life's most important questions from people who should have been able to provide those answers or at least the direction on where to find those answers. That is a real sad commentary on Christianity in America (and Japan apparently) today. I can understand why you'd want to leave that all behind. I sure would.
I think that all the questions you raised are important especially the ones about biblical contradictions. But I also think the most important question, the question (and answer) on which all those other questions and answers must be predicated, is the question, "Is there a God?" And if there is a God, can we live without Him? If there's no God and we can be deffinatively sure of this, then Christian's are some of the most pathetic and pitiable people in history (even Paul says so). On the other hand, if there is a God, knowing his nature and character would be important goals because it's likely that thumbing our nose at him won't get us anywhere (at least not anywhere we want to go).
At the end of the day "religiousity" is a very poor substitute for answers and an emotional "conversion experience is a poor substitute for true salvation.
I have a book here written by an Indian guy who was raised Hindu that really had an impact on my worldview, how I understand God, and answered many of the most philosophical, theological, and practical questions that I had - many of which you have asked throughout your life as related in your anti-testimony. The book is called "Can Man Live Without God?" and it's by Ravi Zacharias. Maybe you've heard of it or read it already. If not, I would deffinately pick it up when you have the chance. I've heard Zacharias speak on occassion and have never heard someone ask him a question that he wasn't able to answer - sometimes in ways that just floor the audience and the questioner. From communist and islamic heads of state to college students and clergy, he's addressed them all. I recently heard him again when he addressed the Brigade of Midshipmen here in Annapolis at the USNA.
His book can be found HERE.
He has also authored "Jesus Among Other Gods: The Absolute Claims Of The Christian Message" and "Who Made God: And Answers to over 100 Other Tough Questions of Faith". You might find those interesting or possibly...ahem..."cannon" fodder for your website. :) You seem to be a serious searcher and someone who is also a lifelong student. Whether you believe in God or not, and whether or not you like the God you do or don't believe in, I hope the God I believe in will bless your journey even if it has been at times dissappointing so far. It aint over til its over.
