I think that religious tolerance (which should not be confused with religious freedom) was more common than some may think in medieval times. One only has to look towards the Kingdom of Sicily in the 1200's.
I don't think so. Jews were outcasts, not owning land--that's why they got the reputation as city-dwelling jewelers, doctors, and other urban professions. Muslims in Spain were driven back to North Africa in the 1200s.
