KR isn't too bad, I have seen much much worse.
Log MAF Freq too, this will tell you if you are closer to maxing MAF out. Can you record gm/cyl air too? That will tell you where you are on the timing table. Only then can you dial in timing.
Your fuel trims are pretty off. Need to do some MAF tuning there. Don't worry about replacing it, you aren't close to maxing MAF out yet. Stock MAF maxes around over 2x where you were on this run. Record MAF Freq and when you are regularly seeing over 11000 Hz, start shopping....
