Don't panic. 
The biggest issue you should expect to deal with is the transition from the deep nuc frames to medium boxes.
I don't live in Sandpoint, but I did spend 17 winters in Pullman WA - but I didn't have bees then.
inch:
I would say that winter conditions in Sandpoint are no worse than in Nebraska, and Michael Bush has lots of bees wintering in mediums in Nebraska.
