'99 318 Plugs and IAC Pictures... What do you think?
I took some pictures of my plugs and my IAC valve. I've been having a little trouble with starting. It starts every time but starts rough when cold and seems to idle just fine. I pulled all the plugs and the IAC Valve. #8 plug looks oil fouled to me and IAC was REALLY Dirty. Take a look and tell me what you think. There are only 10K miles on these plugs
I cleaned up the IAC and plug #8 and it seemed to start better (cold). May be because #8 takes a little time to foul. We'll see.

Yea, I'd say #8 wasn't right. How is your plenum gasket? "Using' any oil? Look down the throat of the TB since you are in there, any oil?
As for the IAC (I'm knocking on wood now) I've never had mine out or replaced and I am at 156,000 miles. Thus, I don't know what to say about how that looks.
All of your other plugs looked normal for used plugs IMO.
FYI, my 2000's original set of plugs were changed at 90,000 miles. The dealer installed stock OEM Champions back in. Those were just replaced by me at 150,000 or at a 60,00 mile interval with Autolite 3923s. While the D ran fine before both plug changes, the plugs did look all used up visibly both times (and should at that level of miles/usage). Why did I wait so long? The D ran fine and I wasn't excited about doing them myself (looked difficult to get to the back two.) However having done it myself this last time, I will be changing them at least once a year from now on (at my milage, that's about 28,000 miles per year.)
