Jesus 1. The first spirit to be born in heaven was Jesus, (Mormon Doctrine, page 129.) 2. Jesus and Satan are spirit brothers and we were all born as siblings in heaven to them both, (Mormon Doctrine, p. 163; Gospel Through the Ages, p. 15.) 3. Jesus' sacrifice was not able to cleanse us from all our sins, (murder and repeated adultery are exceptions), (Journal of Discourses, Vol. 3, p. 247, 1856.)
I googled this topic and came up with this site. I was told these very things by a Mormon I used to work with and got to know very well. He also told me that salvation is through works and not the blood of Christ alone. Other things that he told me are in the article from the link.
Nothing you quoted is Church doctrine or Canon. Those are beliefs held within and among members of teh Church, which beliefs difer as much as my Fathers Southern Baptist congregation beliefs' differed among each other.
