Thank you for attaching the pages! 🙂 The page About the Author is not necessary for your trial manuscript unless you choose to include it. Does it appear in the table of contents? If so, then you would need to include it. Otherwise, you would not need to include it in the manuscript, and there would be no need to send that page in the photocopied pages you would include with your manuscript.
The cover/jacket material is not included in the trial manuscript. 🙂
Hope this helps. 🙂
