Boanerges, I would gladly oblige. I want to make it clear though that I'm doing this by request and that the posting of items from the Catechism is in now way an attempt on my part to proselytize or seek anyone's conversion in respect with this forum's rules. With that said:

CCC 1846
The Gospel is the revelation in Jesus Christ of God's mercy to sinners. The angel announced to Joseph: "You shall call his name Jesus, for he will save his people from their sins." The same is true of the Eucharist, the sacrament of redemption: "This is my blood of the covenant, which is poured out for many for the forgiveness of sins."

CCC 127
The fourfold Gospel holds a unique place in the Church, as is evident both in the veneration which the liturgy accords it and in the surpassing attraction it has exercised on the saints at all times:
There is no doctrine which could be better, more precious and more splendid than the text of the Gospel. Behold and retain what our Lord and Master, Christ, has taught by his words and accomplished by his deeds.
But above all it's the gospels that occupy my mind when I'm at prayer; my poor soul has so many needs, and yet this is the one thing needful. I'm always finding fresh lights there; hidden meanings which had meant nothing to me hitherto.

CCC 1968
The Law of the Gospel fulfills the commandments of the Law. The Lord's Sermon on the Mount, far from abolishing or devaluing the moral prescriptions of the Old Law, releases their hidden potential and has new demands arise from them: it reveals their entire divine and human truth. It does not add new external precepts, but proceeds to reform the heart, the root of human acts, where man chooses between the pure and the impure, where faith, hope, and charity are formed and with them the other virtues. The Gospel thus brings the Law to its fullness through imitation of the perfection of the heavenly Father, through forgiveness of enemies and prayer for persecutors, in emulation of the divine generosity.

Here are a few passages that can give you a feel for what we believe. Asking, "what is the RCC's position on the gospels?" is much like asking our position on salvation...complicated topic no matter how it's explained, and yet so simple. We believe we are first and foremost saved by grace according to Eph 2:8. Many arguments floated by Protestants suggesting that we don't believe this are strawman arguments. For it is by the merits of Christ that one is saved:

CCC 981
After his Resurrection, Christ sent his apostles "so that repentance and forgiveness of sins should be preached in his name to all nations." The apostles and their successors carry out this "ministry of reconciliation," not only by announcing to men God's forgiveness merited for us by Christ, and calling them to conversion and faith; but also by communicating to them the forgiveness of sins in Baptism, and reconciling them with God and with the Church through the power of the keys, received from Christ

We obviously have differences in regards to items such as imputed righteousness and the role of good works in which we differ, but there are some important areas where our agreement is critical. Such areas are the person of Christ and His unique qualifications which would make the Mormon "Christ" unfit, and the understanding of what it is we are saved from, an understanding that eludes Universalists. There are many areas in which our definition of the gospel agree. We can discuss the disagreements civilly I hope.
