If you want to go into the Sistine Chapel don't wear shorts -
Take out a mortgage first too
My tips:
1) Metro is great and cheap. Buses are also excellent and they even have little electric ones for the narrow roads. HOWEVER: despite their tremendous contributions to culture and civilisations, Italians haven't yet grasped the largely-germanic concept of "space". So be prepared to get behind your shoulder if leaving a crowded train at a busy station. They WILL try to cram on before you get off.
2) Not
just the Sistine Chapel, but for the whole of the Vatican: wear trousers and make sure your girlfriend is respectfully covered. I saw plenty of people being turned away from St Peter's. They have changing rooms and lockers, so if it's a hot day you can show up in shorts and get into your trousers.
3) The Basilica on top of St Peters: do it! We took the steps the WHOLE way. Took a while, but you get the full experience then. And the lift only takes you about halfway anyway. The view is phenomenol.
4) There are a lot of free museums... I have a feeling that all museums are free to tourists but I could be wrong.
5) Contrary to the propoganda spread by Pizza Hut et al, pizzas don't necessarily have tomato-sauce and/or cheese! In fact, I would say that only about 50% of the classic topping combinations have both. Italian pizzas rock, but I have seen a few funny faces pulled at Italian pizzas.
6) Buy some bigger trousers... you WILL come back 4-stone heavier. The food is really THAT good.
