That's all of the options. FWIW, we do try not to spread options for the same thing across multiple pages, so usually when you've found "all you can find" that's often all there is.
I'm not sure what you're referring to by "sitemap generation report". Are you expecting to be contacted by email when the sitemap is generated? We don't do that, it just happens automatically every other day.
You can view your sitemap by adding "sitemap.xml" to your forum URL.
You may need to submit your sitemap URL to Google in the first instance, which can be done using their webmaster tools.
In terms of limits on what is generated/included, in your screenshot you can exclude certain content types from appearing in the sitemap.
