In the JVN calculator, the current draw is how much current your motor will be drawing to lift the specified load at the specified arm length. Stall load is the maximum load the motor can lift at the specified arm length. To find out what your stall current would be, plug the stall load into the "Arm Load" box (F8) and look at what your current draw changes to.

Assuming your 333:1 reduction is already built and you're moving the arm around, I wouldn't worry about limiting the current of the motor by any means other than a fuse in the PDB (which you have to do anyway). Choose a fuse that is less than the stall current determined in the method above and you'll be ok.
