You worship by entering the church, lighting a candle, venerating (honouring) the holy icons by kissing them, then taking part in the services. If you are an Orthodox Christian, you can also take part in Holy Communion and other sacraments. In the Eastern Orthodox Church, while the Virgin Mary and the Saints are venerated, they only worship Jesus Christ as God, since Jesus is part of the Holy Trinity (Father, Son, and Holy Spirit). Icons and saints are venerated, not worshipped.

Orthodox Baptism is the sacrament (or mystery) by which persons become part of the Holy Orthodox Church. It can be administered to infants, childrens, or adults. It consists of a triple immersion in water, in the name of the Father, and of the Son, and of the Holy Spirit. It is always joined to the sacraments of Chrismation and Holy Communion (the Orthodox Church practices paedocommunion, or the communion of infants).
The Trinity is exactly the same, ie. Father, Son, and Holy Spirit.
