The WBC breakfast is a croissant (or similar), bowl of fresh fruit, yogurt and full drink service. But most people are still too full from the (IMHO excellent) dinner to eat it. I don't know why you'd skip steak to have yogurt a few hours later, but YMMV. As for the rest of your post, I won't even bother to address...

As for the previous poster, yes, there are appetizers served before the salad. These change on a very regular basis and are essentially amuses-bouche. But I promise you won't go hungry.
