Jumping in as well...
Up until about a week or so ago, every semp I've ever seen with leaves pushing the plant up like that were from over watering, but last week I received some plants that I know were very dry. They also showed the same arching, so I think its fair to say that the condition can occur from either situation. It's definitely a sign of stress. Getting the plants out of the sun was a great move. I would advocate misting during the coolest part of the day - be very careful with the watering. I've been getting very good results with misting daily until the soil surface turns dark from dampness, then stopping.
If there is a substantial root on the rosette, be sure it stays in contact with the ground or in the ground. Your planting technique sounds "right on".
I agree with Sandi. It can take a very long time for the leaves to straighten out. Be gentle with the plant and don't try to force the shape back to normal. Wait for the offsets if you need to.
