The wiki has all the rages in their ROM data order with the old names and new names, but I'm not sure if it's the same as the menu order.

On the topic of an indicator for whether or not you have the rages, I think the absolute optimal, though most likely impossible/incredibly difficult, would be to add a "Shiny effect" when you encounter it, like in pokemon, but I understand this would be incredibly difficult at best.
