Augustine did have a time when he considered Manichaeism during his pagan life. He rejected Manicheaeism long before his conversion. While still a pagan he first converted to neo-platonic thought while teaching in Milan. After his conversion he renounced his teaching position in Milan and returned to Hippo. While at Hippo Augustine did make reference to the Manichaen position when he wrote an apologetic against them. To suggest that in these works he tried to blend Christianity and Manichaeism is just a silly assertion that has no historical basis. Augustine was profoundly impacted by the epistle of Romans, he had access to it and other Christian writings. It should be admitted that he was influenced by platonism and neoplatonic philosophy as many of the other Church Fathers were. He was also influenced by Stoicism since he remained unmarried throughout his life. Manichaeism simply was not a part of Augustine's thinking after his conversion.
Augustine never once used the term "unconditional election" in his writings. While he refered to election, nowhere did he use the term "unconditional election." That would be reading a 17th century debate back into the 5th century and would be totally unhistorical. Augustine's main issues involved a "just war" and the issue of "original sin." The concept of original sin came out of his debate with the Pelagian heresy. However, some scholars think Pelagius actually did teach prevenient grace (see wiki on Pelagianism). The issue of the teachings of Pelagius are in doubt because his works have not survived. He is generally accused of denying the concept of original sin.
