I think that the Encyclopedia of Mormonism states exactly the ideas that seem to be obfuscated:
**“The Father existed prior to the Son and the Holy Ghost and is the source of their divinity. In classical terms, LDS theology is subordinationist; that is, it views the Son and the Holy Ghost as subordinate to and dependent upon God the Eternal Father. They are his offspring.”
"The Son and the Holy Spirit were “in the beginning, with God,” but the Father alone existed before the beginning of the universe as it is known**. He is ultimately the source of all things and the Father of all things, for in the beginning he begot the Son, and through the instrumentality of his agent, the Son, the Father accomplished the creation of all things."
“The Father, Elohim, is called the Father because he is the literal father of the spirits of mortals (Heb. 12:9). This paternity is not allegorical. All individual human spirits were begotten (not created from nothing or made) by the Father in a premortal state, where they lived and were nurtured by Heavenly Parents.”

There is no lack of clarity about Christ’s sonship. Jesus is the Son of God in at least three ways. First, he is the firstborn spirit child of God the Father and thereby the elder brother of the spirits of all men and women as God the Father, known also by the exalted name-title Elohim, is the father of the spirits of all mankind (Num. 16:22; Heb. 12:9; John 20:17). Thus, when Christ is called the Firstborn (e.g., Rom. 8:29; Col. 1:15; D&C 93:21), Latter-day Saints accept this as a possible reference to Christ’s spiritual birth.

Fundamental to the teachings of The Church of Jesus Christ of Latter-day Saints is the concept that all human beings were born as spirit sons and daughters of heavenly parents before any were born as mortals to earthly parents. Latter-day Saints believe that the eldest and firstborn spirit child of God is Jehovah and that it was he who was later born with a physical body to mary as Jesus Christ.
