I am sorry, for some reason I thought you wanted to replace the injectors, but I was getting it confused with another thread. Napa has a complete set of injector and fuel rail o-rings, which is what I ended up going with. It was special order for me, but that just meant I had to wait a few days to get it in store.

FEL-PRO Part # MS949181 This is the LIM gasket
There is no listings for an UIM gasket, so I believe you will just use a gasket maker on it. Not sure if the coolant fittings use orings or not, but you will see that when you get it apart.
There is a small heater hose that comes from the area on top of the water pump, curls around, and goes under the alternator, to the fitting I mentioned. You pull the alternator off, it will be staring right at you.
My thread on it: L27 Lower intake manifold gasket replacement.
I don't see a throttle body gasket listed either for you. But be ready to scrape gaskets, as I believe the UIM for you is goop sealed to begin with.
Look through my list, and if I think of anything important, I will add to it.
