Good points.

Justification and salvation are slightly different aspects of a restored relationship with God. 

Faith, working through grace. 

"Judgment" is used in different senses in the Bible.

In one place Jesus says if a sinner doesn't give up his ways we should eventually "Rebuke him".

That's pretty "judgemental" by some standards today.

There is final judgment which is God's alone, and there are the judgments we must make as Christians to help one another grow closer to God.  Those must be done charitably, properly, with the highest intention possible, after much prayer, perhaps consultation with a well formed authority, prayer over the relevant points in the Catechism etc.
