Well since you haven't had any luck, I'll throw in my 2 cents. I'm not sure what you are looking for. like Farrar, my kids learn how to use the mouse by playing games on pbskids.org. for free programming, I am using code.org with my oldest. I hear Scratch is free and kid friendly. You can also try Khan academy (because KA seems to have everything ). MIT also has some free courses.
