First LST ever

Looks good, I'm agreement with mouse about using something a bit thicker to tie them down with. The thinner the wire the more chance it has of cutting through. After a few days you will probably need to adjust it again.

You'll be fine. I've noticed it a little easier to keep the plant centered over the pot by planting to one side and bending it over rather then planting right in the center but not a real issue by any means. I would recommend continuing to tie down the branches as they start to stretch.
