Help me identify O rings in UIM/LIM gasket kits!!

Hi I'm about to replace my upper and lower intake manifold gaskets on my 2000 Pontiac Grand Prix and wanting to know exactly where all these o rings are supposed to end up BEFORE I rip it all apart..........these are the two kits I purchased to do the job....if someone can help me to identify each o ring, that would be awesome!....I want to do it once and do it right!

With the Felpro LIM gasket kit on the left.....it looks like there's a thermostat gasket and o ring, six bottom fuel injector o rings, the aluminum lower intake manifold gaskets, four side rails, BUT I'm confused where the two orange o rings go and the other two different size black o rings???

With the dorman UIM gasket kit on the right....it looks like there's a plenum gasket with black tube attached to the gasket, 12 o rings (assuming 6 for the bottom fuel injector and 6 for upper fuel injectors), a EGR valve gasket, a thermostat w/ new o ring, the blue o ring looks to go between the throttle body and plenum, BUT unsure where the large orange o ring goes and the two other equal sized black o rings???

Also, on a side question does the tube that is attached to the plenum gasket, does it get installed anywhere inside the plenum??

THanks to anyone and everyone ahead of time!

Should be 2 orings for the PCV valve. One small one that fits over the actual valve, then a larger one that goes in the UIM where the cap screws over it.
