It's more like gold powder, but yes, those are the ones. All they
really do is compensate for vertical misalignment of chip pins by
providing something for them to push "into". Otherwise, that
misalignment compensation comes from the springiness of the
lowest-sticking pins. I've successfully used a PLCC base with no
rubber/gold sheet.

It's
possible to use the bases without those pads, but you have to be
careful. A programmer doesn't become useless when those pads become
unavailable.
That said, it'll be a while before they become unavailable; there are
a lot of them out there.
Are we talking about the same thing? the small black rubber looking
sheets with gold wires embedded in them?
