It would take more than a day to see the entire vast ruins of Pompeii. The minimum amount of time you should set aside to visit a few houses and the Roman Forum in the heart of the ancient city is two hours. More than three or four hours can be too tiring, especially in the summer with soaring temperatures and little shade.

There is no direct public transportation from the Amalfi Coast to Pompeii or Herculaneum. You need to reach Sorrento and take the Circumvesuviana train from there. Taking a tour that includes transportation from Positano or Amalfi is a much less stressful and time-consuming option.

Yes, though we don't recommend doing so. By trying to fit both sites in one day, you would have to rush your visits. Instead, see these two archaeological treasures on two separate days to explore at a slower pace.
