Gym Leaders and badges are probably something you should avoid. That's not to say you can't have a tournament or something as part of the story, or even as your characters main goal, but again, it needs to be implemented differently.
For your table of elements, the default elements for anything seems to be fire, ice, electricity, earth, air, water, light and dark. You can probably include nature/plants, metal and non-elemental as well. However the important thing to realize is that dragon, ghost, bug, fighting aren't really elements at all. Several RPGs might have them as an enemy type that has a set of weaknesses, but the idea of having them as elements that attacks can be infused with is so idiosyncratic that its a lot more obvious that you're copying pokemon when you throw them in.
