Its not a Wooly Senecio. I'm not sure what it is, maybe Blue Chalkstick plant.
Don't repot again and don't water. After succulents and cactus are repotted, they shouldn't be watered for at least a week to give the broken roots a chance to heal. The soil is drying quickly because of the terracotta - drying takes place all the way around the pot, not just on the soil surface. But when you do water, make sure the soil has absorbed the water by sticking your finger in an inch or so or using a bamboo skewer.
It may look much worse before it looks better but as long as its not rotting, its rooting. Water only when the soil is completely dry. The pot is very deep so use a bamboo skewer to see what's going on at the bottom of the pot. Shove it all the way to the bottom, let is sit for a couple minutes and pull it out. You will be able to see/feel where the moisture is in the pot and how much moisture there is.
