Sorry I forgot to answer your other questions!
In the West, Catholics make the sign of the Cross from left to right. Eastern Catholics, make the sign of the Cross from right to left. If you became Catholic you’d probably be Latin rite, so like in the West.
We can pray through memorized prayers or our own words… there are prayers that are encouraged like the Rosary, which is very powerful. We can also pray in our words as well. Most Catholics do both I think. Catholics can also go to Adoration (and non Catholics are welcome to attend too!), where the Eucharist (which we believe in Christ, truly present, and bread and wine are no longer present in substance only in appearance) - is shown in a “monstrance” (
en.wikipedia.org/wiki/File:Monstrans.jpg) and people can come and pray before Christ. The Eucharist (the Host) would be in the center of the monstrance (which comes from the Latin word meaning “to show”). This is very powerful as well and personally I’ve received much help from this practice!
The Mass for us is the highest prayer. It’s more than a prayer, it’s an offering of sacrifice (the Sacrifice of the Cross, is presented before us. It’s not a re-crucifixion, but an offering of the one eternal Sacrifice to the Father. Spiritually, it’s like we’re at Calvary). There have been Saints who have seen the spiritual reality of the Mass, with the Angels, Mary, being there.
We don’t always ask the Saints to pray for us. We can pray to God directly too. The reason we ask the Saints to pray is because they are close to God, and it’s like how we ask each other to pray, only the Saints’ prayers are more powerful cause they’re in Heaven

we believe we’re all part of one Church, and it’s God who makes intercession possible. Mother Mary’s prayers are very powerful because she’s His Mother. (We say “Mother of God” not because we believe that Mary was there before God, but because Jesus is God and His Divine and Human natures can’t be separated. The early Church said this, to protect against heresies against Christ).
God bless!
