I added MAIN MENU in there because if you don't have one you definitely should. Default-selection PLAY MOVIE, next CHAPTER SELECTION, next AUDIO SETUP, and finally COMMENTARY which takes you to the Commentary menu. And I don't think the text is overused, and the STAR WARS logo I used is indeed a font if a font is needed (SF Distant Galaxy Symbols, the number 8 is the vintage STAR WARS logo, the regular letters are Aurebesh in lowercase and Naboo writing in uppercase. SF Distant Galaxy isn't a particularly good Star Wars font, the best for that is Star Jedi, but the Symbols variation is extremely useful).
Of course, it's your baby, and do with it as you please. Personally (and this is another suggestion, do what you want {as if you wouldn't}) I'd make more "normal" chapter names, but that's just me, everyone else seems to like them. I like chapters without names personally and I don't see the point of chapter inserts.
