By "sub-pages" do you mean fragments? There probably has to be an anchor directly attached to a heading. I don't think anyone knows what the exact cutoff is, or if there are other variables. Mine tend to be h3 on pages with no h1.

Which is it? You can influence named anchors.
"Sitelinks" are generally the most popular 4-6 pages linked to from your home page, but usually only appear when a site is dominant for a search query. Usually, a site is dominant for a search on its own domain name, so Sitelinks will appear then, but results vary greatly on how important a site is for a given query.
"Named anchors" are sections of a page. Check out this early discussion of them, where the vocabulary wasn't quite precise because we hadn't seen them before, and we at first thought they were a variety of Sitelink....
