Welcome to the forum..so exciting to hear of your new puppy..yes we need, I mean want pictures..please.
Sounds like you have a lot already planned out, definitely do the fanconi testing, for peace of mindā¦and crate train for house training but also for the puppy's sense of his own cave and space they actually end up loving having a place to retreat to when they get tired or what not...
Has the breeder done any potty or crate training? If so, ask her/him what tactics they used, so you can continue on in their steps (of course only if you agree with their tactics).
My basenji doesn't ring a bell, but bats at the door if he needs to go out, even in the middle of the night and he does it loud enough for me to hear, but yes, if you put a bell on the door, on a level where he can reach it, then touch the bell each and every time you go out with him, he will pick up on that real quick. Otis will even take his collar of the hook and try to put it on himself, if he gives up come up to one of us and throws it on the floor in front of us like he is saying.."put it on, I want to go out"..very smart.
Search and ask on the forum, there is lots to learn and lots to laugh about ..they are an amazing breed, you are in for a treat..again, Welcome.
