Whether one must believe that Jesus is God to be saved (at the time of conversion) is debatable. However, as time goes and a new believer gains knowledge of scripture, I think it would be likely that one would start believing in His deity, and I would definitely not recommend anyone to maintain the position that Jesus is not divine. Consider the following:
Rev. 3:10 has Jesus saying He stands at the door of the church, and "if any man hear My voice and open the door, I will come in to him and sup with him and he with Me." This means that Jesus is omnipresent, and lives in the hearts of men (many references) which proves His deity.
John the Baptist said "He existed before me," which shows that the only pre-existing human is divine. Reference Phil 2:6 saying "He existed in the form of God" prior to His incarnation. If this isn't quite enough, we have Jesus saying "I am He" referencing Isaiah 41:4, 43:10, 13, and 48:12, where God Himself is saying those words, meaning He is God and their Savior. So if Jesus is our Savior, then He is God. There are many great teachings on the web on the deity of Christ, if one just searches for them. In Acts and Romans, the "Spirit of Christ" is equated with the "Spirit of God," and it goes on and on.
At the time of conversion, people are usually ignorant of the teaching of scripture. Although there may be many heresies believed at the time, and many hinderances to sanctification, it doesn't mean they aren't saved. It simply means they are immature believers. If a person begins to repent of their known sins, and start trusting that God will deliver them from their sins by His power, then they have begun to obey Jesus' command to "repent and believe the gospel." Isn't that enough for someone to start their walk with God?
