Pictures with questions/comments of Intake Manifold Removed

[msvx95]

I've just finished removing the intake manifold and there are some parts I need to order. I will post a few different pictures with questions.
I've noticed a lot of caked oil as you will see in the pictures.

First set of pics: Manifold off, is my IRIS valve bad? Should I replace the whole part or does it have an o-ring?

Second set of pics:
I just replaced my IACV not too long ago, but it is still giving me a code 24.
I see a seperation in the insulation on the wire for the plug. I don't know how difficult it is to splice and replace this plug? Any thoughts? Should I replace the whole wire harness as shown in the picture? What is the harness part number?

Third set of pictures:
The EGR hoses, which one goes with the egr valve as pictured just above my thumb? There are two inlets and not sure which one goes where

Last set of pictures:

These show the parts I was going to replace anyways. The hose broke on my AACV, so I have a new hose and new AACV that will be installed.
The knock sensor shows a crack in the housing. I will replace both sensors.
Tons of oil....wow.

Is my PCV connector bad too? Look at this thing.
