Streams and Trilogy

In the SD
On the question of “slander,” the rabbi wrote that the words are said as a criticism of all sectors and schools, and there is no school that does not have some kind of criticism.
This led me to ask, “What is the right path for a person to follow?” And the rabbi brought me back to the trilogy.
The thread was getting more and more complicated with Mohran from Breslav. And I just wanted to know a simple and minor thing. (Before I really push the building)
A. I pray 3 prayers a day, set times for Torah and try to observe the halacha as written and as written. I have no problem with the Jewish religion and I agree that there is criticism of certain matters. Therefore, I tried to take from each stream the good in it with the addition from my father’s house and what I added from my own. But where does the trilogy meet me in my ways of life and what am I supposed to change?
on. When there is criticism of everyone. Why are the “Jews coming” being purged in the “Ken Tamim”??
third. What is the alternative? After all, every person in our time must be counted, even retrospectively, in some stream. His children will study in institutions of this stream and be educated at its feet. I personally see the moderate Haredi institutions as a minor evil. And with this I wanted to know whether, in the Rabbi’s opinion, there is another minor evil. Or is there even another alternative?
D. I wanted to understand whether the trilogy is actually supposed to present a new halachic ruling that is different from the Shulchan Aruch?
I hope I’m not bothering you. And I’d be happy for even short answers.
