The Brass "five books of Moses" revisited

This is the standard reading of Nephi's list of what is included in the Plates of Brass (1 Ne. 5:11-13):

And he beheld that they did contain:

(1) the five books of Moses [Genesis, Exodus, Leviticus, Numbers, Deuteronomy], which gave an account [in Genesis] of the creation of the world, and also of Adam and Eve, who were our first parents;

And also (2) a record of the Jews from the beginning, even down to the commencement of the reign of Zedekiah, king of Judah [parts of Judges, Samuel, Kings, Chronicles];

And also (3) the prophecies of the holy prophets, from the beginning, even down to the commencement of the reign of Zedekiah; and also many prophecies which have been spoken by the mouth of Jeremiah [Isaiah,  parts of Jeremiah, Hosea, Joel, Amos, Obadiah, Jonah, Micah, Nahum, Habakkuk, and Zephaniah; plus other prophets like Zenos and Zenock].

In other words, the Brass Plates essentially contained the Old Testament, minus the post-exilic books, plus some other books we no longer have.

As discussed in "Moses and the Exodus: Where the Book of Mormon parts ways with the Torah," I doubt this. In that post, I emphasized that Nephi makes it sound as if all five books of Moses were about the Creation and Adam and Eve, when in fact only a few chapters of Genesis touch on those topics. I've just realized that another reading is possible, one in which Nephi is summarizing the content of each of the five books in turn:

And he beheld that they did contain the five books of Moses, which gave an account of:

(1) the creation of the world,

and also (2) of Adam and Eve, who were our first parents;

And also (3) a record of the Jews from the beginning, even down to the commencement of the reign of Zedekiah, king of Judah;

And also (4) the prophecies of the holy prophets, from the beginning, even down to the commencement of the reign of Zedekiah;

and also (5) many prophecies which have been spoken by the mouth of Jeremiah.

The main question this reading raises is why these would all be considered "books of Moses." If we allow ourselves a little flexibility with the punctuation, though, we can modify our reading slightly:

And he beheld that they did contain the five books:

(1) of Moses, which gave an account of the creation of the world,

and also (2) of Adam and Eve, who were our first parents;

And also (3) a record of the Jews from the beginning, even down to the commencement of the reign of Zedekiah, king of Judah;

And also (4) the prophecies of the holy prophets, from the beginning, even down to the commencement of the reign of Zedekiah;

and also (5) many prophecies which have been spoken by the mouth of Jeremiah.

In the King James English which the Book of Mormon so often imitates, a relative clause with which can refer to a person, as in the Lord's Prayer: "Our Father, which art in Heaven . . ." (Matt. 6:9). Under this reading, the five books of the Brass Plates would be: (1) Moses, (2) Adam and Eve, (3) the Jews, (4) the Holy Prophets, and (5) Jeremiah.

Note that I don't think we can assume from the Book of Mormon alone (taking the Bible to be unreliable) that Adam and Eve predated Moses. "Our first parents" is also used to refer to Lehi and Nephi at one point (Hel. 5:6), so it does not necessarily mean the first ancestors of the entire human race.
