Sure disclosure is required. There is no requirement; however, that an
invention be your _whole_ product. For example, most automobiles have
thousands of patents involved in their creation. It is entirely possible,
even commonplace, as I said in my mail, that one or more portions of a
product represent practice of patented inventions, and one or more _other_
portions represent trade secrets.

That depends. Obviously, trade secret protection can be very effective for
processes involved in manufacturing physical goods. In software, it depends
on whether what you are treating as a secret becomes widely known (after
which, self-evidently, it is no longer a secret!) For example, if one where
to keep the mathematics behind MD5 a trade secret, it is plausible that it
would never be "figured out" just from examining object code that implements
the algorithm. It doesn't matter if it theoretically could be done, just
that it hasn't actually happened.
