Ok, You are still pretty early on in the game.
To tell you thr truth don't worry about Kuat. You are only allowed to go there really really late in the game.
As for Dathomir, well Bring ONLY Zann AND Urai, NO ONE ELSE. I mean, sometimes you might include some sneaky personel w/o looking.
Hint: Make sure you have quite some credits in hand, you would want to bribe some nice walkers after the first step of the game.
