I don't necessarily use the TOC, but having proper headings means the nook can tell me how many pages are left in the chapter; otherwise it sees only 1 long chapter in the book.
The fact that the ToC doesn't have h tags is not a problem. I just put them in and then let Sigil generate the ToC. I then fix it up from there and I'm good to read.
