In answer to your first question, I would suggest playing it.
For the rest:
Name: Bumblestump
Race: Khajiit
Class: Alchemist and Assassin (poison daggers, yo)
Personality: Idiot Savant -- absent minded, oblivious to social cues, loves collecting butterflies regardless of their alchemical properties to the degree that he will stop what he's doing to collect their wings, but also one of the most skilled blade masters and alchemists of his time.
SC or Imp: Whoever has the nicest alchemy set for him to play with unsupervised.
Special Skills: Underwater operatics (still working on that one, though -- the last three performances resulted in near deaths); gold divining (with his nose, for he can smell gold from fifty paces, no matter where it's hidden); and narcolepsy in direct sunlight.
You're welcome.
