emndarmic,
Those are good choices in moderation. There is nothing wrong with that. I don't do fruit roll ups, cookies, sugar cereals, white bread or stuff like that either here. However, I do allow it in the house as treats or what have you. Again, in moderation.
Before you do anything.. talking to the doctor is the best bet. Normally they will tell you which diet your child should follow. I have heard of many doing something like WW which is like calorie counting and so forth. You don't want to totally cut out a food group though.
