Earth Trekkers has provided a pretty good travel guide for Rome.
The primary things to do in Rome include: the Colosseum, The Roman Forum, and the historic city center (1 day), Vatican City and The Borghese Gallery (1 day).
According to Wikipedia, "Rome is the capital city of Italy. It is also the capital of the Lazio region, the centre of the Metropolitan City of Rome, and a special comune named Comune di Roma Capitale." "Vatican City (the smallest country in the world) is an independent country inside the city boundaries of Rome, the only existing example of a country within a city. Rome is often referred to as the City of Seven Hills due to its geographic location, and also as the "Eternal City". Rome is generally considered to be the "cradle of Western civilization and Christian culture", and the centre of the Catholic Church."
