This URL (http://www.gotquestions.org/Satan-fall.html) has a ton of information with Scripture references. I recommend going there to start your own research.
The Bible clearly states that Satan was one of God's most prestigious angels before he fell from Grace. He lost his eligibility for grace because he was prideful and wanted to be God.
I would recommend starting with Isaiah 14 and reading that chapter. The problem with man made theology is that it can easily distort God's word. If the church or Christian denomination you belong to doesn't preach from the Bible, I would use a high level of discernment.
We'd like to believe that all Christian pioneers are 100% faithful to the Lord, but that's not possible, and generally untrue. Ever heard the phrase wolves in sheep's clothing?
Be blessed!

"If traditional Christianity claims Mormonism is wrong on this topic, then where did Satan come from? Where do angels in general come from?"
Traditional Christianity claims that Satan was created by God, as were all angels, as was everything.
- John 1:1-3 ESV In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things were made through him, and without him was not any thing made that was made.
And we believe that Satan IS a fallen angel. You can check out this thorough answer here: https://christianity.stackexchange.com/a/2612/11471
