Do I need a heatsink for this transistor?
At currents close to its rating, a heatsink is recommended, because the TO-220 package sheds heat mainly through its metal tab. Check the thermal figures in the datasheet for your operating conditions.
Can I drive this transistor directly from an Arduino pin?
Not directly. The base needs a series resistor and enough base current to saturate the device at a high collector current, and a microcontroller pin cannot supply that. Use a driver stage or a suitable smaller transistor to drive the base.
