Any research done on the Narrative of Zosimus & Lehi's "Tree of Life" Dream in 1 Nephi (LDS scripture)? Similarities? More info on N. of Zosimus?

To answer all five of your questions.

1. Yes, there is more information.

2. There are English translations. You can find a rendering of the text in English at newadvent.org. that appears to date to 1896¹. There is another English rendering here with a helpful introduction.

3. If not a correlation, there is some similarity.

   A twenty-two page analysis of text, as compared to text in Nephi, is available on line through Brigham Young University. The author is John W. Welch, who wrote "The Narrative of Zosimus (History of the Rechabites) and the Book of Mormon" in Book of Mormon Authorship Revisited (1997). The conclusion is cited from that paper/chapter.

   Despite the many similarities set forth in this article between the Book of Mormon and the Narrative of Zosimus, it is difficult to draw any specific conclusions regarding possible direct relationships, or on the other hand, the independence of these documents with respect to each other. We simply know too little about the authorship and transmission of the Narrative of Zosimus to venture any judgment about the kind of spiritual experiences its author had as compared with the visions and revelations of Lehi. Similarly, we cannot know precisely what influence general literary or cultural backgrounds may have had upon those responsible for composing and transmitting the Narrative of Zosimus, or for that matter, upon Nephi as he recounted his own and his father's inspirations. Perhaps someday we will have greater knowledge to assess what connections if any stand between these two intriguing ancient accounts. In the meantime, however, it seems both reasonable and productive that one continue to study these two texts together. Both deserve greater attention and neither should be erroneously judged amiss against valid ancient Judeo-Christianity. Before the recognition of similarities, such as those between the book of Mormon and the Narrative of Zosimus, it was possible to reserve interest in the Book of Mormon by wondering why no other ancient near eastern books existed which closely resembled it on that score. One need wonder no longer.

4. Other scholars have shown an interest in and done work to give greater accessibility to this narrative. From the BYU paper:

   Dr James H Charlesworth, Professor of Christian Origins at Duke University, Durham NC, has compiled the most complete, published bibliography and has made a thorough study of this long neglected narrative. He concludes that its most ancient portion was written somewhere in Judea, that it was originally written in Hebrew, and that it would be unwise to ignore the possibility that this oldest section is a Jewish work that predates the fall of Jerusalem in AD 70. How long before AD 70 this early material was actually written down is difficult to tell. The traditions underlying many sections in the narrative of Zosimus undoubtedly go back even further.

Dr Charlesworth produced a recent translation into English. (p. 312, same source)

Professor Charlesworth reports having examined in Paris, Oxford, London and Manchester manuscripts of this document written in Greek, Syriac, Ethiopic, and Karshuni. His English translation of Zosimus will appear in Doubleday's forthcoming publication of the Pseudepigraphia, and soon a new edition of the Greek Syriac and Ethiopic texts will be available in the SBL Pseudepigrapha series

5. Jack Welch is an LDS scholar. You can evaluate his theories in that 22 page excerpt, which conclusion I cited. He found it difficult to draw conclusions. He noted that more scholarship is needed.
