Provided you have the fare for the ferry, you are taken to be judged. If you lived a good life, you are taken to the Lethe to drink and forget the worries of your mortal life, and then to the Elysian Fields to spend eternity in bliss.
If you lived a bad life, you are taken directly to Tartarus to spend eternity paying for your crimes.
If you don't have the fare, you are forced to wander the shores of the Styx for 100 years before Charon is compelled to ferry you.

They use the Greek god "Hades," god of death and the Underworld. After death people's souls would travel down to Hades (another term for the Underworld) and would be judged based on their life as a living soul. This judging would determine which part of the Underworld they would be assigned to. You could be judged as a good soul and be sent to the best, most luxurious parts of the Underworld, or you could be sent to Tartarus, the worst of the worst parts in the Underworld, and there your life after death would be an eternal hell.

The Fields of Asphodel Are absolutely part of the Underworld. It is a place where souls of neither good or evil are sent to after death.

Zeus did not "send Hades to the Underworld"; just as Zeus rules the heavens, Hades rules the Underworld.
