Yes, the truck has a knock sensor. And, I've never, EVER heard this truck ping (unlike nearly every non-turbo vehicle I've owned or driven in the last ~15-20 years, which all seem to ping on purpose). That doesn't mean it isn't, though.
I guess I'm saying that shy of a major issue (which you already know you'd realize from other means) I don't think you're getting any REAL information from the plugs.

i.e. subtle color variations mean nothing without a chop since you can have no real idea what is causing them or when.

On the pinging - I highly doubt it's pinging (for more than a split second that it takes the knock sensor to compensate by telling the ECM to change timing).

But we're talking in circles now. Motor is running right, got fresh plugs, kids are happy - LIFE IS GOOD!

I did see a video on youtube of someone doing this for their 2005 WRX which I think would be identical.. correct me if I am wrong. My wife and I are going to do this over the weekend.. or so is the plan. Take a look and tell me what you think.

Find someone with small hands and get some small/low profile tools. It's a tight fit.

Can do a compression test while you're at it if you're curious.

I actually couldn't get my coil packs out without jacking the motor up.

I suggest leaving the coil packs plugged in to the harness, just pull them out and set them out of the way. Breaking the tabs is a stupid way to have to buy zip ties.

Though, breaking the tab on a coil pack sucks less than breaking the tab on an injector...
