Although this deals with housebreaking and I'm not sure how 100% realistic the schedule is (good outline though), sleep is mentioned here.
Good pointers in here:

While there is truth to the saying, "a tired puppy is a good puppy," one needs to keep it in perspective of the age of the puppy. Tiring out an eight/nine week old puppy the same way one would a six month old puppy would not be healthy for the eight/nine week puppy.

While beginning a schedule and routine for her is a good idea and in her best interest, at the same time you are going to have factor in the needs of her age.
