I know as Catholics there are some things we are required to believe (or at least stay silent if we don’t) and some things he don’t have to believe. How do we tell the difference? Sounds like communion in the hand is ok to disagree with, eh?
Sometimes people have a hard time telling the difference (between revelation and mere practices, etc). For example, some do not know that married priests exist, and you can tell this by the line of reasoning they use. An easy thing for basics is to read the CCC. There is no official “list” out there. Um, well, I do think some enterprising person has placed a list of doctrines stripped from the Fundamentals of Catholic Dogma on the internet.
Basically, you want to hold with faith the things that the Church teaches as revealed. Also, you should have faith about what God revealed in scripture and various other, sort of dependent things, like the canon of scripture. Knowing what the Church teaches as revealed takes time and effort. No one ever hands you a brochure, unfortunately (or not).

God has provided well enough for us to come to know him, I’m sure about that. Seek him, and you will find him, even if it takes too long from a human perspective.
But maybe you are really asking about communion in the hand? I assumed this was a general question. Okay to disagree with how? Most parishes in the world distribute on the tongue.
Oh, eek, the CCC is the Catechism of the Catholic Church, sorry for using the abreviation without explanation!
