Gimbal is just something that every setup and animation team has to deal with. If your character is this simple, I recommend rebuilding the arm skele. At the shoulder, make three(3) joints one on top of the other. Name them (ArmRotX_1,ArmRotY_1,ArmRotZ_1) seperately. Then you only have to rotate one axis for each joint. If you put in IK, make it at only the ArmRotZ_1 bone to the wrist, and not to the ArmRotX_1.
And when you skin the character, only akin the arm at the ArmRotZ_1 joint as well, theres no need to skin the other two.
It makes your workflow hard to get used to at first, but I think the final result is alot easier on your sanity.
