Sorry for not being clearer...you've got three productions:
- Cups & Balls, final load of candy
- Bunny production, from undecided prop
- Square Circle, which is a utility prop that allows you to produce other props for the show, or just produce a bunch of stuff for the routine.
My suggestion is to keep the giveaways to the end of the show, and produce them out of the Square Circle, either as the only thing you take out of the Square Circle, or the last thing. Since the design of the prop in the Mark Wilson Course looks like a top hat, it might be a good routine to show it empty, put some "ingredients" into it to make candy (silly stuff that would never make candy in real life) and then produce the candy and give it out.
Including a final load of candy at the end of the cups & balls would just duplicate the Square Circle. So instead, end the cups the traditional way with the large balls. Also, depending on how many people are in an audience, the amount of candy you can produce from the cups & balls is much smaller than what you can produce from the Square Circle. And you always want to make sure every kid gets something!
There are plenty of other tricks to replace the coloring book with, just nothing exactly like it. It's possible kids will have already seen it, that's why I suggested dropping it when you can. But for your first few shows, you've got it, use it and see how it plays. It's visible for smaller audiences.
If you're going to turn the wand into a handkerchief, that's fine. But usually kids want to see something important like a wand come back. You could easily "find" it later in the Square Circle.
The toughest thing about entertaining family audiences is being able to engage kids and their parents. That'll take awhile for you to figure out what works for you. You've got a good start with some classic tricks, get in some rehearsal time and do a good job!
