Baptism. It is required before any other sacrament is received. All sacraments give grace.
Baptism IS an important Sacrament for Catholics. It is the first Sacrament of 7 that we receive. Here is a link that will explain about the seven Sacramants of the Catholic Church. http://en.wikipedia.org/wiki/Sacraments_of_the_Catholic_Church It is the MOST important Sacrament for Catholics because without it we would not be able to receive the other six Sacraments.
Baptism is the sacrament of initiation in which one becomes a child of God. It is impossible to receive any other sacraments without first receiving Baptism. Sacraments are real, physical acts but they are also symbols of the grace which is received from God. Trying to receive another sacrament without Baptism would only be going through the motions.

Roman Catholic AnswerBaptism is the sacrament by which one becomes a child of God and capable of being pleasing to Him, and receiving His Grace. No other sacraments can be received until one has been baptized. To be baptized, one must not be previously baptized, and, if an adult, one must be instructed and accept the faith. Confirmation is a sacrament that is received after baptism, and it "completes" baptism. One needs to be baptized and in a state of grace to receive confirmation. Both of them are considered sacraments of initiation. Baptism is a sacrament of the dead (one is incapable of being in a state of grace until after baptism) and Confirmation is considered a sacrament of the living (one needs to be in a state of grace to receive it. Anointing of the Sick is another sacrament given to deal with physical illness.
Eucharist (Communion) is one of the four sacraments of initiation along with Baptism, Reconciliation and Confirmation; it is called a Sacrament of the living as you must be in a state of grace to worthily receive it. Sacraments such as Baptism and Penance are "Sacraments of the dead" because you are dead in your sins when you receive them, and they restore you to a state of life.
