I have a book coming out with Christian Focus this November, called "A Christian's Pocket Guide to how God Preserved the Bible."
In it I lay out my answers to some of the questions you posed in your review.
However, I should say that the book is not an "academic" one.
I expect that you will not agree with all of my conclusions in that book, but I'm grateful for your review here and I'll think more about how I might sharpen a response to your questions in future work.
In the Lord,
