I have the EXACT, same issues as you. Same codes, same rough idle same symptoms. Replaced O2s. I dont get misfire codes but can feel slight ones. Do you get a vibration through your steering wheel aswell during idle and cruising from your engine running rough?
Here is my to do list:
Clean intake valves (walnut blast)
Replace Air intake to stock oem air box.
Replace cats to catless dps
Secondary cat delete
