There is no such thing "president of Jerusalem". Jerusalem, like New York, Vancouver or San Francisco, is a city and therefore it has a mayor but not a president. The current mayor is Nir Barkat, a businessman, who was elected in 2008. He was preceded by Uri Lupolianski.
No. The mayor of united Jerusalem has been a Jew ever since Israel passed the Jerusalem Unification Law. Prior to that, Jerusalem had several mayors in different districts, most of whom were Jewish and some who were Muslim. Prior to 1967, East Jerusalem had a Jordanian Muslim mayor and West Jerusalem had an Israeli Jewish mayor. While the mayor of Jerusalem has consistently been Jewish since 1980, there is no rule on the books that prohibits a person of any other religion (most likely Muslim) from being the mayor. It is unlikely, though, given that Jews represent over 60% of the city's population, that a non-Jew would be elected.
