This is pretty much what I've done.

Bookmark that site as a place to NOT get information.

Which is right? I tried putting on an amount towards the lower end

It looks like you've got it right.

For the record, what I've done is put about a dime size blob on the heat
sink, and a rice grain size blob on the processor.  The blob on the heat
sink is spread out and wiped off so it fills the scratches, pores, and
imperfections in the metal.  I've also seen where people will polish the
heat sink to a mirror finish, and not put paste on the heat sink.  On the
processor, take a razor blade and spread out the paste over the raised part
only.  The result should be a fairly thin coat on the processo
