Hi...it's late so I'll keep this short for now...welcome Jing & Wrigley. (I have a "Wrigley" too, he's a 19 year old corn snake.)
You definitely need to address the cage temps.- that might be part of the reason he's being a fussy eater (though it also goes with the territory of keeping a BP).
The other issue is all the handling before he has settled in to eat regularly for you...it's not recommended, as it can disrupt their instincts on food, especially when
they're young. Snakes do feel vibrations so it may be that he's less startled because it's a signal that he recognizes as your presence (as opposed to the scary
appearance of something unknown). But we want you to be successful so I have to say "feeding is job ONE"- not sure what you mean about "Barb's feeding
technique"? As far as keeping his tank warmer, you can insulate the back & sides (w/ various things), &/or you can add an overhead heat source to help, but do
work on that a.s.a.p. or you'll have a sick BP & that's even less fun than a BP that's not eating. If you don't already have a thermostat controlling your UTH, you
need that too, like "yesterday".
