Four days at Aspendell is a luxurious amount of acclimation. Take advantage of it, and go higher as much as you can, especially on days 3 and 4. Horseshoe is a great choice for the night before the climb.
Bulldog's advice is all right on, especially as to Consultation Lake instead of Trail Camp. You can always go to Lone Pine Lake if you feel really good after summitting, but it is a real pound down there from TC or CL, and much better done fresh in the AM. Everything else seems like exemplary planning. I wish more people on the trail were as prepared. Good work.
