You are indeed very fortunate that your parish has maintained some of the treasures of Catholic culture. My present parish has too for which I feel very fortunate. Other parishes I belonged too had almost no resemblance to anything Catholic.

Some other cultural and devotional practices which spring to mind:
Collecting Holy cards
Writing AMDG or JMJ on the top of the page of assignments in Catholic school.
Yearly missions
Almost all Catholics wore a crucifix or a Miraculous medal.

Writing AMDG or JMJ on the top of the page of assignments in Catholic school.

JMJ - Jesus, Mary, and Joseph. I'm pretty sure. Is AMDG the Latin for "For the Greater Glory of God"?

I've started reading Sister Faustina's Diary, and she seems to have JMJ starting out a lot of the entries.

Collecting Holy cards

You used to have a place to keep them -- in your missal. Including the cards they used to send with acknowledgement notes for attending a wake, with a prayer for the deceased on the back.
