Welcome to the faith!
The ritual and the “do and don’t do” of the Mass can be a bit to get used to. When I began attending the Latin Rite after being in the Ukrainian-Byzantine Rite, I had a bit to get used to as well!
Depending on how much reading you like to do…I really recommend Pope Benedict’s books, especially “Feast of Faith” and “The Eucharist, the Heart of Life” and “The Spirit of the Liturgy” they all were written when he was Cardinal Ratzinger, and they’re all excellent for really understanding everything.
The GIRM (General Instruction of the the Roman Missal) is also fantastic, though it is an instruction book, so the writing is a little dryer (but not terribly). It tells you what to do where in the Mass, it also tells you what the priest should be doing.
There are also the documents from Vatican II on the Liturgy, which are very helpful.
A fun book, to help with understanding the attitude behind the ritual, is The Catholic Passion by David Scott.
I hope this helps!
Pax et Bonum,
