1) Have you updated your COBB AP and ATR recently? That logging rate is very very slow. With the updated firmware, you'll get faster resolution.
2) Which fuel tables did you alter? Generally, you should alter all of them appropriately. I think Abilor covers this in his tuning guide. For instance, the OL tables, make them 11.0 across the board and the PT tables, make them 11.0 in the areas above 1.0-1.25 calculated load (depending on your commanded closed loop exit) and interpolate 5 rows up. Make your knocking tables a little richer.
3) Knock isn't that bad. It'll fix itself once you calibrate the MAF properly. Right now, the car is flowing more air than it is metering (as noted by the leaner than commanded AFRs) and is therefore applying a timing advance that is too aggressive given the airflow/fuel which is causing you to knock.
4) For calibrating the MAF, I would multiply any MAF scalar reading above 100g/s with 1.05 (11.5/11.0=1.05) and do another datalog. There are areas where you reach 11.8 so it may require another slight calibration.
5) Fixing boost will require altering WGDC but by the looks of it, the turbo isn't even breaking a sweat hitting 18.5PSI so you may want to keep it there for more powah. There is also room to keep a more aggressive boost profile to redline if you wish. That taper down to ~14PSI must really make the car feel like it falls on its face.
