Diff'rent Strokes for Diff'rent Folks?

Popkin asks:

different schools request different materials from applicants. For instance, I notice that Northwestern only asks you to send them a "complete CV along with list of references." In such cases, will the committee be annoyed if you send them more than they've requested? Is it a bad idea to send your letters or your teaching portfolio or whatever to a department that hasn't specifically requested those materials?

My first year out I sent everything to everyone with little in the way of results. Last year I sent each department only what they specifically asked for, but didn't do any better. So I don't really know.
