Looks ok so far. You'll need more light as the plant gets bigger, optimum is 7-10,000 lumens per square foot of plant.
You'd be suprised how rough you can be with plants when moving them around, so long as you don't pull roots off they're usually fine. Might sulk for a day or two but MJ's a tough old bird, she'll bounce back if left to her own devices.
Be sure not to overwater in that big pot, it'll probably take her a week or more to drink all that that soil will hold (that her roots can get to) and she'll survive a drought far better than a flood.
