The middle name is not optional, according to New Grove. However, its spelling is variable. Most CD covers, Wikipedia and Last.fm listeners seem to prefer 'Jakob', with a 'k'. New Grove gives that spelling in square brackets, meaning it's an optional variant. The 'Jacob' spelling is less popular with assorted online sources and forums, but is the one the New Grove gives as the preferred spelling. So it's what I'm running with, too
