The sacrifices described in Ezekiel are the gifts brought by the Tribe Leaders, and the Pessah sacrifice. The inauguration of the Mishkan initiates its holy status, and the Pessah sacrifice initiates the holy status of Am Yisrael. The second part of the haftara discusses the status of the Nasi - the monarch - who is responsible for bringing sacrifices to the Temple. The monarch parallels the priest - the monarch represents the nation in the Temple, while the priests represents the interest of the Divine.
