Question about Halls of the Mountain King by Kobold Press
 

I am planning on running this as my next adventure. I have all the Kobold Press datasets except the New Paths.

What datasest do I need to be able to run this well? Are there datasets out there to cover the creatures/NPCs from this adventure?

Basically I just need to know what I creatures and such I will need to add on my own? And if there are any suggestions to help me run the game better.

Thanks
