I would imagine that lip reading on a stage is difficult under the best of circumstances, and it being staged in the round only complicated things. To your detriment, this is beautifully staged so all sides are included.
That being said, I think your best bet would be either the 200 or 300 sections, and as near the center as possible.
I hope it proves to be an enjoyable experience for you, as it's a beautiful show.
