How do you determine if a particular torque should be considered + (positive) or  (negative)?

Question 2

Is it possible for a moving object to be in equilibrium?

Answer to Question 1

By convention a torque that could produce a counter-clockwise rotation is +
(positive), a torque that could produce a clockwise rotation is  (negative).

Answer to Question 2

Yes. If the sum of all forces and torques add to zero, the object will be in equilibrium
even though it may be moving at a constant velocity.
