Ah! That's good to know. 

Does anyone know if you can use either hand to cast spells? I vaguely remember in one of the earlier books Dresden said that you draw in magic with your left and cast with your right? Does anyone remember if this was an actual thing?

Draw in energy with the left and send it out with the right, which is why most wards and defensive spells are actually cast with the left hand, while offensive spells are cast with the right.
