New Young BP Wont eat.

[Yggdrasil]

Hi, Me and my son have got ourselves a pet ball python.
He is pretty young, and we have had him about 5 weeks.
I made some mistakes at first :
1) improper hides, i only had one half log hide
2) glass was not blacked out
3) No Thermostat on heat pad (after 2nd day i measured 115 in the hollow log hide, i adjusted by moving pad off tank and installing a cearnmic tile. Now have thermostat on it)
4) tank too large.
5) heating pad too small for tank.


So the snake has not eaten since we got him. We attempted the first feeding 6 days after we got him, on f/t fuzzy. he snached it up without much effort and began to eat, then I put the top of my critter cage on and the light (now changed to heating element) it scared him and he dropped it.
Every time we have offered him after that he sniffs a little but doesnt show interest.

I have made the following changes:
Made flower pot hides 1 on each side.
Installed a nice hydrofarm thermostat for the warm side (the most stable part of the cage)
blacked out the back of the tank with internet green pics.
switched to an infrared element instead of a heat lamp
installed an internal, external, humidity thermometer.

So here's what I think may be going on.
First of all, this tank was given to us, it is a critter keeper around the 40 gallon size. My wife got the heat pad which is rated for 20-30 gallons.
The temps are:
Hot hide: 93 (heating pad under this and aquafarm thermostat probe in the hide)
Cold Side (75 - 86) there is no heat pad on this side (measuerd by the accurite walmart outside probe).
Ambient (center tank) , 85 -87 Measuerd by the accurite walmart inside .
Humitidy (all over) 40 -60 % ( just pour some water on the aspen daily and it stays around 40 %.

I think the cold side is too cold (he spends a lot of time on the cold side).
Tank too large.
Environment noisy (childrens room, 3 hours of loud children daily), ( Movies played on the computer at night to put kids to sleep).
change of feeding method, the guy at the pet store told me to come by for a live mouse , (I opted to go for f/t because i was afraid the mouse would hurt the snake. I am curretly trying to feed fuzzy f/t from petco).
Too many environmental changes, I have been rearranging the tank to accomodate for new hides, thermostats and some foliage, (I have not made any changes for 2 weeks now) the last change was adjusting the hydrofarm system.
hot hide was still too hot even after initial adjustments, it was adjusted by moving the heating pad off to get to 95 (and hotter) temps until i put the thermostat in there.

Please advise, I am learning how to be a good caregiver for this snake, obviously I have floundered around a bit but luckily these are pretty hardy snakes. ( i hope). I never realized it would be this tough to set up the snakes environment, however, we are learning to become great herpotologists.
Here are the changes im consider:

I'm considering going to live mice.
I am also considering a second heat pad and hydrofarm thermostat on the cold side (to keep it at 80).
Thanks!!.
