It is time!

Hi all! I'm biting the bullet and potting my Albo cutting, it's been propping for around two months. When I got it it only had the bottom aerial root, so all of the other roots and the top aerial have grown within that time. I have the moss soaking. I'm potting into a chunky mix of perlite, orchid bark and coco coir. I was water propping so I know I have to be super vigilant regarding roots dying and root rot. I have rooting powder- should I dust the roots before potting? I'm going to ensure the top aerial root goes into the moss pole securely. I'm kind of freaking out because this is my baby and I have invested so much mental energy and good vibes into it, I just want it to be a happy lil bubba. Any other things I should be doing or any advice? Thank you lovelies!
