Yes, the meadow at 11.2 is the spot. And if you are prepared do the 16 mi from Guitar (15 from the tarns) and skip Trail Camp, you have an extra day to stop at Kearsarge Lakes your first day, making it much easier to get to 11.2 the second, and Wright the third.
As for your last day, a very popular itinerary is an alpine start to get you on top around sunrise, very easy to get down the last 11 to the Portal for that burger same day.
