What do I need to fly a "N" registered?

Hi there!

I have the opportunity to fly a "N" registered aircraft here on this
side of the Atlantic.
Just wondering if I need to have a FAA "ticket"?
(I have a UK CAA PPL)
Also, which are the aircraft documents that I should ask to have
a look?
The FAA issued documents are the same as ICAO?
Certificate of Registration, Certificate of Airworthiness,
Aircraft Journey Log Book, Radio License,
or the arrangement is different.

Thanks,
