I submitted my application online and it says I need to mail in the references with passport photos and supporting documents. This will include a copy of my mother’s British birth certificate as well as my US birth certificate. Do I need to go ahead an include my actual US passport or just a copy at this point?

I did a successful UKM application and have only ever sent copies of documents - just be sure to include every page of the passport in colour.
