The Muratorian Fragment lists 22 of the 27 NT books as canonical. It dates to 170 AD. The document is called a fragment because portions of the document have been torn off. The well known biblical scholar Westcott states that the missing books were probably included initially because the document is torn where they should have been listed.
The answer to defeating the heresy of JW's is the Word of God itself... not more heresy.
There are many, many ancient Jewish history books and historical Dead Sea Scrolls that are fascinating to read. Enoch is one. The Book of Jasher is another. Both books are either quoted or are mentioned by name in the bible. The Gnostic heretics wrote a number of works by the same names though. So be careful. The gnostic versions of ancient books are easy to determine, but you do have to be aware of them and be careful.
You can pick up the Book of Jasher by Ken Johnson on Amazon. It is sort of a cliff notes version, is a good read, and will fill in a lot of the early details of humanity written about in Genesis.
Ancient history books are not "lost books of the Bible". That is a marketing ploy. They were never considered inspired. And as such, believers read them with a grain of salt noting that they may not have been preserved exactly as originally written.

Testimony of the 12 Patriarchs is not referenced in the bible but is also available. It was considered by skeptics to be written by Christians several hundred years after Jesus lived because the theology is essentially Christian and not Pharisee. When a portion was found in Qumran with a BC date, it changed that view for many.
