what was right in the eyes of Yahweh

The word "eyes" here represents seeing, and seeing represents judgment. Yahweh saw and approved of Joash's actions. See how you translated a similar phrase in 2 Chronicles 14:1. Alternate translation: "what Yahweh judged to be right" or "what Yahweh considered to be right" (See: rc://en/ta/man/jit/figs-metaphor)

all the days of Jehoiada, the priest

This idiom means "as long as Jehoiada, the priest, was alive." (See: rc://en/ta/man/jit/figs-idiom)
