How are Roman Catholics born again?
We are "born again" through the waters of baptism. Info:

Must Roman Catholics participate in the Eucharist in order to be saved?
The Eucharist is one of our Sacraments. Our most precious one, as it is the Body & Blood of Christ. We believe it to be so, because he said so in John 6 and because he instituted this practice at the Last Supper. It has also been the tradition passed on from Christ through the Apostles and was never questioned until quite a while after the Reformation. Luther certainly believed in the Eucharist.
Are Roman Catholics children of God, then children of the devil, then children of God, depending on whether a mortal sin was committed, confessed, and forgiven?
I don't know about being "children of the devil," but we are out of a state of grace if we have committed mortal sin that has not been confessed. Now, if someone has felt guilty and has every intention of going to confession as soon as possible, but doesn't make it, and dies, then we are not able to make judgements about it. We can never make judgements about it. It is completely up to the divine mercy of God. The Church does not purport to judge -- only Christ is our judge.
Do Roman Catholics believe that believing that Jesus Christ died for one's sins, was buried dead, resurrected, and bodily ascended into heaven and confessing the same to others is enough to gain ones entry into the Kingdom of God? Why or why not? If not, what has to happen.
Considering this very testimony is what is in the Nicene Creed (which the Catholic Church wrote as a whole), of course we believe in Christ dying for our sins. As for "confessing the same to others," we certainly must confess our belief in this very creed in order to be receive the Sacrament of Confirmation. I, myself, received this Sacrament in 2005, where I proclaimed my belief in these truths before a congregation of over 1,000, and before Christ and all the angels and saints in heaven.
Does this allow me to "gain entry" into the Kingdom of God? Well, I believe that if I continue to live a life for Christ, that I will be able to be with Him forever in heaven. I certainly strive to continue to live my life in a way that is pleasing to God. If I renounced my beliefs either verbally or by action, then I would not necessarily have the right to expect that my prior baptism and confession would cover all future sin. I must repent each time I sin and if it is a mortal sin, it is our belief that we should seek confession to a priest to receive absolution for this. For day to day failings, I do as you do, I pray for God's forgiveness and during each Sunday mass, we confess that we have sinned to our entire congregation and pray for one another. This is a part of the mass (called the Confeitor).
I hope this answers your questions.
God bless,
Michael
