Do I need an insulating washer with a TO-3 heat sink?
For the 2N3055 the collector is connected to the metal case. If the heat sink is grounded or bonded to the chassis, use an insulating washer and thermal compound. Check the datasheet of your specific device.
Should I use thermal paste between the transistor and the heat sink?
Yes. A thin layer of thermal compound between the case and the heat sink improves heat transfer. Tighten the mounting screw firmly so the contact surfaces stay flat against each other.
