Yes, yes, and yes.
If you are a Roman Catholic in good standing who is not in need of confession and who has kept the communion fast, you may receive the Eucharist when you go. It is dispersed from a spoon directly into your mouth. Look up, open wide, tongue in, don’t say Amen or cross yourself.
The only thing you need to know before going is that you may attend and receive as it is a Church in full communion with Rome. Some other things you might

One other thing you might like to know is that all parishes of the Romanian Catholic Church use the Byzantine rite, so you don’t need to make that clarification.
Things that are likely to be drastically different you might need to prepare yourself for include:
That the Liturgy is likely to be most or all in Romanian
That the priest might have a wife and children and his wife, if he has one, is called Preoteasa.
That there is no genuflection. People bow to the altar.
That there is unlikely to be western devotions like Stations.
That you’ll be singing, “Lord, have mercy” a lot.
That it is unlikely to be exactly like you expect, no matter what you expect.
