There was a fantastic DIY video of someone doing a drain and fill on a Gen3 Prius I saw a while back. I can't find it anywhere: PC, Google, YouTube. Anyone know the one I'm talking about?
Its really simple. Just take your time. Make sure to loosen the top bolt first (where you will fill the oil to level) before taking the bottom bolt off. Last thing you want to do is to drain your oil and not be able to remove the top bolt to fill it up. The Manual says something like 3.5 quarts to fill. Mine took about 3.75 quarts with the car perfectly level. Some people say they used the entire 4 quarts. This might not be your case but if it is don't worry. Just make sure your car is leveled.
