I did a quick setup last night and wanted to see if there is any improvements I can make.
I attached the ARC charts and targets.
Levels look good. As Acer suggested, if you run ARC again for any reason, turn your sub down just a hair. However, no point in doing this unless you have another reason to re-run ARC.
Fronts: How close are these to any walls? Possitioning them a bit closer might give you some boundary gain that could help lift the low end a bit... depending on how much you gain, you might be able to fill in some the valley we see in the 80-150Hz range, though the higher end may not gain much.
Surround: Look Great
Center: Looks Great
Sub: I see you set it to Flat, that makes sense based on the graph you posted, if you are comfortable with your subs protection. The main area I would focus is on your subs location. Is it close to a wall or corner? If yes, pulling it out a foot or so may reduce some boundary gain that may help you get better high end extension (currently ARC has set your cutoff on the sub at 80, we like to see it naturally
hit 120 which it looks like it should do). Note, you may end up turning the gain up a hair if you are succesful in losing some of the boundary gain.
To play with your sub, you can use Quick Measure. Note, after playing with Quick Measure, if you didn't make any changes you will need to re-upload your last ARC configuration as Quick Measure wipes out your old ARC settings. Of course if you did make changes, you would want to re-run ARC again.
Popping noise: What version of firmware are you on? And was the experience repeatable? Is it possible the PS3 simply sent a burst of garbage while switching modes?
