Yes, just reload.
And no, you don't need to "grind" for a fight because you're about to be drown by exp when you enter Lower City.
Reload when you're invited to the audience hall, don't forget to bring Wyll and Karlach.
In my case, I skipped the Wyrm rock entirely, and straight to Basilisk Gate.
You can meet Gortash right away or chase Orin.
In my point of view, everyone in the Wyrm Rock are innocent bystander.
Nobody needs to die even if they're hostile.
My advice is when the time comes for you to kill Gortash, chug some invisibility potion and get pass through the Flaming Fist soldiers stationed there. If you talk to them you'd know that Flaming Fist is being manipulated by the Three Vermin's Chosen.
