Do I need to use star washers or are regular washers ok?

You always should use Star Washers between the GND cable and Alternator .. The Star Washer will help "Dig" into the case of the Alternator and the same holds true on the Block or Chassis attach side.
You use the Washer on the other side between the Bolt Head and GND cable. So sequence....
Bolt Head->Washer->Cable->StarWasher->Alternator

Good luck.....
