Saying talmud torah kineged kulam dosent apply anymore is not changing any mitzvah, only talking about its level of importance. So its not a contradiction to nitzchiyus hatorah.
2) The ikar of Nitzchiyus hatorah applies even after moshiach comes and also techiyas hamasim. See nidah daf 61, rishnim there. (reb elchonon) and at length kuntres ????? ?? ???? ???? ?? ????? ????? ?????, and ???? ??? ?’ ??? ??????? ???”? – ????? ???? ???? ????? ???
I was just saying that it was mentioned that the gaon says that tznius is as important for women as torah is for men. Arizal argues that torah is not the main avoda. Chassidim who follow the arizal 1) dont follow the vilna gaon 2) dont hold the same about limud howrah as the people who follow the gaon as seen in tanya, and all over sifrai chassidus, the stress on davening, tzedaka, etc (like igeres 9) so you need another proof for chassidim about the “ikar” of tznius. The fact that satmer is very machmir more than litvaks very nice, it dosent make it the most important thing in yiddishkiet just like the fact they wear shtraimels dosent either, or the fact they dont vote or make sure to say tachnun on 5 iyar even if there is a bris.
