Yes to all if the above. The WPPSI is not as extensive, but that's partly because young children are more difficult to assess accurately and stably.
BTW, there are actually extended norms out there for the Binet, too, but the WISC has stronger backing from the publisher for their use.
The WJ does generate IQ type scores (GIA), but it tends to favor fast, verbal kids. There is no real equivalent to the WISC GAI score, that lessens the impact of processing speed and working memory (cognitive proficiency).
