Well, you could create a new project folder, then save the 1st project with the 'Save As' option, and save it to the NEW project folder, making sure to check the box for copying the audio over to the new project.
This would give you a complete copy of the 1st project, in a brand new folder, and would have all settings as well as audio copied over from the 1st project.
I also recommend changing the name of the project, during the Save As, to match the name of the new project folder you created to place the project in.
Edited - I HOPE I understood your needs, and hope I have given a way to meet them with the above.
