Re the OP: the order of service tends to be follows:
Penitential rite: basically a spiritual clearing of the decks before Communion - confession and forgiveness. It usually finishes with the Gloria and a short prayer. Stand for this.
Liturgy of the Word: a reading from the OT (except in Eastertide when its from Acts), a psalm (to which the congregation normally repeats one verse as a response), a reading from the NT, a reading from one of the Gospels and then the sermon. Sit for this except the Gospel, for which stand.
All then stand to say the Nicene Creed.
Prayers of intercession, sometimes finished off with a 'Hail Mary'
Liturgy of the Eucharist - preparation & thanks for the bread and wine or a hymn. Sit. Followed by a prayer over the bread and wine and preface to the Eucharistic Prayer and the 'Sanctus' (often sung)-stand. Then kneel for the Eucharistic Prayer (one of four possible prayers - One is the longest, Two the shortest, all involve the invocation of the Holy Spirit to make the bread and wine the Body and Blood of Jesus and the words of Jesus at the Last Supper).
Stand for the Lord's Prayer, followed by the Peace and then invitation to Communion, including the 'Lamb of God' prayer - kneel. if you're not Catholic you can't usually receive Communion at Mass, but you can go up for a blessing if you want (just bow your head with your arms folded across your chest). Then a couple of prayers after Communion, followed by blessing and dismissal.
The only points other than the (optional) Hail Mary when Mary is likely to be mentioned is in the Penitential Rite and in the Eucharistic Prayer - unless it's one of her feast days.
