Well, neither of these phrases are associated with Derridean deconstruction. "The death of the author" is a kind of slogan these days, I suppose, but I don't think Foucault's intent was as cut and dry as you make it out to be (he was responding to Roland Barthes by the way.) Could you tell me what you think it means before I try to respond to the three or four ways I've heard it interpreted?
Reader-response criticism, started by Stanley Fish, is a way of reading texts through time and monitoring multiple reactions to texts through time and then commenting on their interaction. I can give you an example if you want.
Derridean Deconstruction absolutely depends on a certain understood meaning and then scrupulously works through the text where that meaning is somehow missing, absent. The meaning can't be what it says, or what it says can't be what the author meant.
Now, Derrida, when he deconstructs, concentrates on philosophical texts, when he looks at literature, he doesn't deconstruct, he does literary criticism (see "Acts of Literature"). It's pretty fun too.
