I'll defer to any Mormons as to the specifics of what Mormons believe (and any nuances between specific Mormons themselves).
I'm much more familiar with the various Lutheran church denominations than I am with the Church of Latter Day Saints.
The Church of Jesus Christ of the Latter-Day Saints (otherwise known as the Mormon church), is a Christian Church. It recognizes God the Father, His Son, Jesus Christ, and in the Holy Ghost.
It recognizes the King James Bible to be the Word of God, and the most correct translation (as far as it is translated correctly), the Book of Mormon (a partial translation of Plates left by people living here in what is now America (both North and South America) also to be the Word of God for those people, in the the Doctrine and Covenants, the Word of God for people living today, compiled by contemporary prophets of God.
All of these scriptures agree and support each other. Each stands as another testimony of God and Jesus Christ.
It recognizes that God has NOT abandoned Earth, and a living prophet exists today (Dallin Oaks, who also acts as President of the LDS Church). The message is the same: A witness of the power of God and Christ, and the influence the Holy Ghost has upon each of us, if we let it.
It seeks out the good in all things.
We believe that men will be punished for their own sins, and not for Adam’s transgression.
Nevertheless. death comes to all men. I do not consider that a 'punishment', for Christ's Atonement answers for this, allowing all who are obedient to the laws and ordinances of the Gospel to conquer death just as Christ has done.
First, there must be faith. Without that, nothing further can happen.
Second, there must be the principle of repentance. We can learn from our errors, forgive ourselves, attempt to make right whatever it was we wronged, and seek the forgiveness of Christ, our Lord.
Baptism by immersion is the first of the ordinances, marking membership in the church and your willingness to follow the Gospel.
For the LDS Church, this is where it starts.
