1. What were the major beliefs of Judaism and how did they influence Western culture?
A: The major beliefs of Judaism were monotheism and righteousness. These Jewish beliefs became markers of the Western tradition: human beings are separate from nature and must struggle against it; human beings have. particular relationship to a Supreme Being, who watches over them.
2. How was Islam meant to complete what Judaism and Christianity had begun?
A: Both Christianity and Judaism are monotheistic: they believe in one God, not many. Through Quran revelation to prophet Muhammad by God through the angel Gabriel, Islam completed the role of the two other religions. Islam corrected deviations that were introduced in Christianity and Judaism. In addition, Quran, as the last holy book, detailed the morals and the rules for life that should be considered by all believers in God--Christians and Jews.

What do you mean by "Islam corrected deviations that were introduced in Christianity and Judaism?"
"Quran, as the last holy book,"
The second question is very biased. What makes you certain Islam is the correct term? Are your meaning Quran, or Shara Law instead of Islam?
What makes this question to me so biased, is that of the five pillars, Christianity has far removed itself from those pillars: Love one another, Love God, Jesus is God Manifest to humans, the Holy Sprit rules with God and Jesus, as one over his kingdom.
Islamic texts depict Judaism and Christianity as prophetic successor traditions to the teachings of Abraham. Muslims believe that the text that Christians and Jews use have been distorted through interpretation, and Christians and Jews view the other two as distortions. Here is what I see as the differences in Christian tenets from both Islam and Judaism:
There is only one God
God is three in one or a Trinity
God is omniscient or "knows all things"
God is omnipotent or "all powerful"
God is omnipresent or "present everywhere"
God is sovereign
God is holy
God is just or "righteous"
God is love
God is true
God is spirit
God is the creator of everything that exists
God is infinite and eternal. He has always been God
God is immutable. He does not change
The Holy Spirit is God
Jesus Christ is God
Jesus became a man
Jesus is fully God and fully man
Jesus was sinless
Jesus is the only way to God the Father
Man was created by God in the image of God
All people have sinned
Death came into the world through Adam's sin
Sin separates us from God
Jesus died for the sins of each and every person in the world
Jesus' death was a substitutionary sacrifice. He died and paid the price for our sins, so that we might live.
Jesus resurrected from the dead in physical form
Salvation is a free gift of God
The Bible is the "inspired" or "God-breathed," Word of God
Those who reject Jesus Christ will go to hell forever after they die
Those who accept Jesus Christ will live for eternity with him after they die
Hell is a place of punishment
Hell is eternal
There will be a rapture of the church
Jesus will return to the earth
Christians will be raised from the dead when Jesus returns
There will be a final judgment
Satan will be thrown into the lake of fire
God will create a new heaven and a new earth
It is difficult for me to understand then the question "How was Islam meant to complete...", theologically, as in the above listed tenants, little is left to complete.
So in the answer you gave to the listed question, it is fraught with bias, so any answer you give is perhaps "beautiful" in the eye of the beholder, but I do wonder what type of religious academic would have dared use the word "complete" as describing a religion.
