Could you accept Ringwraiths for Nazgul? Also, I don't believe the city of the dead is a translation for Minas Morgul, rather it means Tower of Dark/Black Sorcery/Wraiths/Necromancy.
Technically Uruk-hai aren't a race. Orc is the race, the "Uruk-hai" are a subgroup of orcs. The word "Uruk-hai" simply means "Orc-folk" in Black Speech.
