Great list - I had all of them growing up. Be mindful of the age though. My uncle (an IBM engineer) got me a breadboard/ciruit kit when I was way too young to understand it, and it was frustrating and turned me off of electronics for awhile. Lego mindstorms was similarly frustrating, though also fun.
