I'd have to concur that the spider bite sounds a lot like a brown recluse
spider bite.  Did you by chance save the spider so that it can be I.D'ed?
 
In any event, I would definitely take the ferret to a vet.  My Mom had a
brown recluse bite a few years ago, and was quite sick for months.  The
doctor told her the venom from the brown recluse can be as deadly as venom
from a cobra.  The bite can be lethal to people, and I would imagine even
more lethal to small pets like ferrets.
