Wow, what an ordeal for you and your horse! It sounds like she has awesome care going on, which is probably the most positive thing about the circumstance! That she didn't seem to cut through 'vital' structures is a good thing too. Hopefully she will make a full recovery!
Once the surface injuries are healed over, I would handwalk her as much as you can as the activity will help her hoof grow in quicker; obviously not heavy activity or work, but as steady as you can.
