I'm too lazy to go look at your roster and figure it out for you. But I can tell you what is working for me in T4. Maybe some of it will be useful, probably not now, but maybe in the future.
JTR is the obvious one.
CLS/Han/Wiggs/Healer
DOT squad - Zader, Nihilus, Sidious, Boba, Tusken Shaman
NS (least useful of these teams)
Thrawn/Deathtrooper/Magmatrooper/Veers/Shoretrooper
A simple team that most people have: Farmboy luke lead with any other 4 rebels. I use CLS and Han but can use Leia Ezra Sabine and Visas Mar. Visas is key but everyone has her. She will work at 3 stars.
If you dont have Farmboy, Ackbar lead works too, but you need to put at least a Tenacity Cross and maybe one set one everyone to work.
The tenacity lead resists the defense down debuff so muti-attackers can go to town without him getting protection back. Can easily get more than 1M damage.
I've had decent luck with Zader lead, Palp, Nihilus, Thrawn and Death trooper. Hit with Zader dots early, kill adds, death mark, hit with Fracture and Annihilate. Rinse/repeat. Use Thrawn to feed Death Trooper or Nihulus.

Currently I keep the teams together based on faction but am wondering if that is not the best use. I have:
Unfortunately most of my success in this raid has been related to the zetas I've collected. Not sure if either of those can do anything without zetas.
Jawa and bountyhunters (detonators stick on lower tiers) do well to. Stick as many detonators on Nihilus as possible.
Deathtrooper/Thrawn/magmatrooper combination is really good as well. Kill adds, put deathmark on Nihilus and go crazy with fracture and magmatrooper.
Just to clarify OP asked about P1. My zzAsajj lead NS do the worst of my five teams in P1. Good in P3/P4 though.
