You asked me to show you where these things are taught in Mormon doctrine. Here are my references: I understand that you don't consider all that I reference as "offical" doctrine, however it is taught within the ranks of Mormonism.
Mormon Doctrine teaches that there are many Gods:
The Mormon Church teaches that there are many Gods (Book of Abraham 4:3ff), and that we can become gods and goddesses in the celestial kingdom (Doctrine and Covenants 132:19-20; Gospel Principles, p. 245; Achieving a Celestial Marriage, p. 130). It also teaches that those who achieve godhood will have spirit children who will worship and pray to them, just as we worship and pray to God the Father (Gospel Principles, p. 302).
Mormon doctrine also teaches that Jesus became a God:
The Mormon Church teaches that Jesus Christ is our elder brother who progressed to godhood, having first been procreated as a spirit child by Heavenly Father and a heavenly mother; He was later conceived physically through intercourse between Heavenly Father and the virgin Mary (Achieving a Celestial Marriage, p. 129; Mormon Doctrine, pp. 546-547; 742). Mormon doctrine affirms that Jesus and Lucifer are brothers (Gospel Principles, pp. 17-18; Mormon Doctrine, p. 192).
Mormon doctrine also teaches that God was not always God:
The Mormon Church teaches that God the Father was once a man like us who progressed to become a God and has a body of flesh and bone (Doctrine and Covenants 130:22; "God himself was once as we are now, and is an exalted man, and sits enthroned in yonder heavens!" from Teachings of the Prophet Joseph Smith, pp. 345-347; Gospel Principles, p. 9; Articles of Faith, p. 430; Mormon Doctrine, p. 321). Indeed, the Mormon Church teaches that God himself has a father, and a grandfather, ad infinitum (Teachings of the Prophet Joseph Smith, p. 373; Mormon Doctrine, p. 577).
