Personally I think many of the books of the Bible have been altered to one extent of another.
I know some folks think that God has supernaturally maintained the integrity of the 66 books we call the Bible... but think about it.
Why would God give a warning to not add or remove anything from Revelation if in fact it could not be done? Kind of like the movie "A Few Good Men."
"If the Colonel gave an order and his orders were always obeyed... then why did they have to move Hernandez?"
If the scriptures cannot be corrupted.. then why the warning?
In order to grant wiggle-room for unbelief.
You'll notice God never makes any item of faith airtight, but always allows a way for the minds of men to turn the supernatural into the mundane.
Otherwise, he'd write "repent" in the clouds at sunset, or send angels to preach to people one-on-one, ...or make the Bible completely harmonious.

Enoch is considered part of the pseudographica. As far as I know, the Ethiopian Orthodox are the only ones who consider Enoch scripture and include it in their canon. There was support for the book, namely by Tertullian who accused the Jews of removing it from their canon because it contained prophecies of Christ. After the Council of Laodicea, it was no longer used outside of Ethiopia.
Your facts are fundamentally correct. I would modify a couple points...
1. 1 Enoch is considered part of the pseudepigrapha, by SOME, part of the Apocryphal Old Testament by others, and part of the Bible by others. Its one of those books that people disagree over its classification.
2. The Ethiopian Orthodox are NOT the ONLY ONES who consider 1 Enoch scripture. For instance, though I consider myself in the Protestant stream, I break with that stream over the casting-out of certain Old Testament books from the Bible for which complete originals are only available in a language other than Hebrew, like Tobit for instance. And just because I am Baptist and NOT Ethiopian, does not prevent me from being one of those who consider 1 Enoch scripture as well.
