Congrats on the new boy.
A few comments -
1. I wouldn't bother trying to feed him till he sheds the first time (he won't eat till then)
2. Make sure his first meal is really small (pinkie would be ideal) this way you can leave it with him overnight without issue.
3. At 88 on the warm side you are getting low you need to get some more warmth try for low 90's
4. What is your humidity? You need it to be higher right now as hatchlings can dehydrate quickly (my pre sheds are on wet paper towels...just to give you an idea)
Good Luck...keep us posted.
