OSAC valve .....that location is 73 only ....in 74 they moved it to the air cleaner (part 1)

not sure what part number 2 is or what it does.

I don't know their technical specific names, but they are part of the EVAC system that cars started using for emissions reasons. I got rid of mine. Did you want to replace them or just know what they are? Go to Rock Auto and should be able to find pictures of the parts under the emissions area

I just wanted to know what they were, and what they did...to see if i needed them.

But if both are just emissions stuff, I will just continue to not worry about them,and later remove them.
