The NT is credible, just look at who it was written by:
1) Matthew (one of the 12 apostles)
2) John (one of the 12 apostles)
3) Peter (one of the 12 apostles)
4) Paul (leader of the early church)
5) Luke (companion of Paul)
6) Mark (companion of Peter/Paul)
7) James (half-brother of Christ)
8) Jude (half-brother of Christ)
9) Author of Hebrews (companion of Timothy, who was a companion of Paul)
I don't think so at all. I think you are judging based on what antisupernaturalist scholars say. Look at who the NT was written by: it doesn't get any more authentic than that!
Not true at all: the gospels were always ascribed to Matthew, Mark, Luke, and John, ever since we have records of them. The fact that the early church never doubted their authorship and the fact that they bear witness to facts that only an insider could know is proof that they were written by who they claim to be written by.
You need to check out some NT resources on this subject because if this is what "NT historians" are saying, then it is simply not true. Here are a few resources:

These are monographs written by world-class scholars which examine many of the issues you mention. I have read several of the books in this series and they are excellent.
Well, the fact of the matter is that most Biblical prophecies were fulfilled during the prophet's lifetime, you are correct. Because of this, it is possible for antisupernaturalists to claim that they were somehow written into Scripture 'after the fact' and get away with it. However, there are some Biblical prophecies that have been fulfilled that it is impossible to fulfill after the fact; for example:
"26 Then after the sixty-two weeks the [
aa]Messiah will be cut off and have [
ab]nothing, and
the people of the prince who is to come will destroy the city and the sanctuary." Dan. 9:26a (NASB)
In Daniel's prophecy of the 70 weeks he has the Messiah dying and then the city and sanctuary being destroyed by the people of the prince (or ruler) who is to come. Christ died in 33 AD and Titus/the Romans destroyed the city/sanctuary in 70 AD. Even by the most antisupernaturalist dating, Daniel was written in the 160s BC (it wasn't, it was actually written circa 530 BC, but we'll just say the 160s for the sake of argument), therefore it would be impossible to go back and write this prophecy into the book of Daniel. Daniel predicts the destruction of Jerusalem and the temple; this was fulfilled in 70 AD.
This is proof of the divine inspiration of the Bible. If you want more proof, you can check here:
