Each decade of the Rosary focuses on a section of Scripture as a meditation.
These are called the mysteries. Out of 20 meditation decades (5 are done each day)
18 of them follow Jesus through the Bible and two are related to Mary (Assumption and Coronation).
Meditations are 20 Mysteries: 18 Excerpts from the Bible + 1 Based on the Bible (Coronation) + 1 From the catholic tradition (Assumption).
That is:
•Jesus 90%
•Mary 10%
•(95% is right out of the Bible)
The Scapular.
Over time, the scapular worn by religious took on the symbolic meaning of the yoke of Christ.
It was a physical reminder to the one wearing it that they had taken up Christ’s yoke
and burden (cf. Mt. 11:30). For the individual who was considering following Christ in the religious life,
he or she knew that a commitment was being made to take up one’s cross in a particular way
— i.e., the life of penance and poverty in following Christ.

As for a crucifix, the Crucifixion is in Every Bible as far as I know.
wearing one or having one on the wall at home is an outward sign
of ones faith. “May I never boast except in the cross of our Lord Jesus Christ,
through which the world has been crucified for me, and I to the world” (Gal 6:14).
