Wittgenstein's most 'existential' remarks can probably be found in Culture & Value.
existentialism is a freedom of choice
Existentialism is a philosophy and postmodernism was an art form/movement

yes
The Existentialism period was from the late 1930's to the late 1950's, roughly. Hope this helped :)
