the rooting hormones may or may not work and if they do it only shaves off a small amount of time -- i used to use it and don't bother anymore and see no difference in results. I'm also never taking cluttings and worrying about 1 or 2 extra days before i can transplant it, ymmv.
once it is rooted it is simply another plant. treat it like you treat all other plants - go light on nutes while light on roots, but it won't take long before it needs a regular diet. Start exposing to normal temps/rh as you don't need to hinder transpiration anymore. Once it is rooted there's nothing left to worry about. Let it form a good rootball that can hold the substrate together for a proper translplant when the time comes.
I think the people telling you to strip leaves off are under the impression this is a recent cutting and missed the fact that you see roots already. Do not cut leaves off at this point. When you initially take a cutting, reducing transpiration and photosynthesis can help, but once you have roots removing leaves will only hinder the growth. Also, you can see it is not necessary to do with your success. I've read completely contradicting things about smaller or larger clones, as well as whether to take from the top portions or lower portions of plant. Unless you see real data on it, don't trust anecdote, because anecdote is all over the map on these things.
you can do things mostly wrong and still have a high success rate in the short-term with small sample sizes, lol, this is the problem with anecdote.
