Do I need a heatsink?
For light loads a heatsink may not be needed, but at higher current or power dissipation you should mount it on a heatsink and check the thermal limits in the datasheet.
Can I drive it directly from an Arduino pin?
A Darlington has high current gain, so a microcontroller pin can switch small loads through a base resistor. For relays or motors, add a flyback diode across the load because these loads are inductive.
