Having hiked Whitney 4 times with midnight starts, I will second wbtravis' suggestions. There is a place above Mirror Lake where the trail takes an abrupt left turn. It's easy to miss because it is outside the beam of a headlamp. If you come to an edge, just back up a few steps and look for the trail turning left. You want to hike in the dark going up, not coming down when you are tired. Leave early enough to be down before dark. Your dayhike permit allows a midnight start and you won't get much sleep from the anticipation anyway. Water is easy to find in the dark because the trail parallels the creek closely in many spots. We like to refill just past Outpost Camp where there is a big flat rock to the right of the trail. It's a nice place to rest and the creek flows next to the rock. You shouldn't need to refill again until Trail Camp. Good luck!
