Sam: Its impossible to plan now exactly what you will need to wear at your start or at any particular point. Temps vary by a lot. Take what you might need for all reasonably expected conditions then suit up at the trailhead according to actual conditions. A good principle to follow is that you should be feeling a little cold at the start, because you will warm up fast. Be prepared to strip off and add on layers throughout the trip.
BTW, I would NOT plan to stay at Lone Pine Campground. You need much more elevation to acclimate. Stay at the Portal at least, or Horsheshoe for even more el.
