Default Identify these parts (gaskets, o-rings etc.)

Alright GM experts I need your help. Im new to the GM 3.8L motor but not new to automotive repair the slightest. I'm doing an L67 swap in a friends 2000 Monte Carlo, the L67 came out of a 98 Regal. Along with some other stuff he gave me this bag of random gaskets/o-rings and I need help identifying them. He doesn't have the purchase receipt.

-One bag I'm assuming is the injector o-rings, there are 6 and all the same size.
-Another has two of the same size o-rings (black) and one larger red - Supercharger maybe?
-No Idea on the rectangular gasket
-Blue "gasket" I can tell is for the TB, but not sure how to use it since the TB and SC are two flat surfaces that mate to each other. It'* about 1/4" thick
-No idea on the other gasket
-What is that silver thing? Almost looks like a shaft that a SC pulley would mate to but I don't know

Thanks in advance for any help.

Is that a sleeve insert for the UIM EGR passage?

On another note, I really don't know why they include it, but the rectangular gasket for the coolant cover on the LIM(under the throttlebody) you don't need to replace. Unless its leaking. Never seen one leak before. It'* a pain in the *** to get a straight razor in there to clean off the old gasket. So I always say don't bother with it.

On the other hand if the intake is off, its a good idea to replace it.

I have just realized that the context is supercharged. What is that doing in there? Is there any place for it in the supercharged environment?

Nope, NOT applicable to the L67 engine. Toss it in the junk drawer.

Good catch sir!
