JTR zeta priority

That actually depend on the squad you're using. You'll need only 3 beside JTR & BB8 (those 2 are a must).
The most recomended are- Finn, C3PO, R2D2, RH Finn, RH Poe
But you'll be just fine with one of- Holdo, ScavRey, RT and maybe Poe

Important zetas(if you're using the toons):- JTR(all), R2D2(all), C3PO(all), BB8(RwtP), RH Finn, RH Poe, Holdo

Not important zetas- the rest

And what about the vets? Since their touch up they seem more viable.

They are not.

They are, you just need to know how to use them.

You can skip JTR's "Virtuous Protector", C3's "Wait for Me!", Hero Poe's only zeta and even R2's "Number Crunch" unless you plan on taking him to higher relics (before going for JML).

Holdo is debatable too before unlocking GL Rey.

Not once, anywhere, in any mode, have I seen the Vets viable. They’re cannon fodder.

Have you seen ahnaldT101 video about beskar mando with veteran han solo get 4/4 in phase 4 in LSgeoTB. I think that's pretty viable (I agree that that's not with JTR, but they're viable)

And I also have seen things with them in a resistance team, I just can't remember which team and which opponent
