If your fiance is a Jew, why not ask him? Probably both of you should go together to his rabbi for counseling and information about marriage.
As far as traditional Jewish wedding ceremonies, it depends on to which branch of Judaism your fiance belongs and which ethnic group from which his family comes. You can probably find information like that on the wedding websites, including lots of pictures.
A marriage license is issued by the state government. It's not a religious document but can be signed by the person legally performing the ceremony, whether religious or secular (like a notary public).
Even in the more liberal congregations, I've never heard of a wife becoming a Jew simply thru a marriage ceremony. But that's something you can discuss with the rabbi.
Every couple should have deep discussions about their religious beliefs before they are engaged. Those beliefs will effect how you live and raise your children.
