I like the ideas, except for the bboard.
Most people do not classify their postings, and this will be less likely if we have one category per package...
Besides the technical description of the package I would have some non tech abstract (a sales pitch). I would also have a list to "white papers" that explain it in more detail (when they are available). Finally I would have some distintive presentation between packages, like in jakarta.apache.org, where each project has its own logo, and to some point its own personality.
