How is the Lutheran church government set up? what is the differences between the ECLA and hte LCMS?

Mark's answer is basically correct. To expand his point, the full-blown episcopal polity is more prevalent among Lutherans in Scandanavia, the Baltics, Russia, and some areas of Africa. These churches have also retained or restored "apostolic succession." In 1999, the ELCA signed a Concordat with the Protestant Episcopal denomination in the US, whereby all future ordinations would also be carried out with apostolic succession, with rare exceptions. Since that time, ELCA bishops, and even some LCMS presidents have become more like "real" bishops, rather than just administrators, often wearing copes and carrying croziers during official ceremonies.
