Yes, they have to be approved before they are visible.
The categorization is pretty lame. Ideally, it would be rewritten with the categorization package (but that's 5.0, and I was on 4.6.3).
Search integration has not been added in. But Goggle seems to like the package a lot. I've gotten a lot of Google traffic on these pages since I set it up. :)
Reminder: I threw this package together, so it's a start, but it's still rough and dirty. I did the absolute minimum amount necessary to get it working as shown at http://www.safe4all.org The only thing that's unnecessary, I guess, but nice to have is that it does use the content repository.
