Laurie, I'm on board with Ursula's advice to just enjoy your blooms for now and not disturb the plants by re-potting until spring. Just ran across these pictures of some of my Phals in past years and thought to pass them on.
The significant thing to think about is to always mount or pot your Phal with the crown on an angle or sideways, not facing upwards. If the leaves don't drain water out after you've watered the plant, it's an invitation for crown rot. These plants grow naturally with the leaves hanging downwards, on the trunks and branches of trees. So no matter what you choose to pot or plant them in (or on) be sure the leaves will drain. You can see in this picture I had mine in a large variety of different pots and mounts. All had one thing in common - plenty of ventilation to supply air circulation to the roots.
Another thing to not stress about is when they want to stick roots out of the medium, up into the air. This is natural and a normal thing for these plants (and most orchids in fact). My Phals sometimes looked to be crawling out of their pots.
Last thing to think about - the way Phals are presented in the stores, with the plants facing upwards and the flowers staked up vertically - this is completely unnatural for these plants. The flowers will naturally cascade downwards very gracefully and face out towards you to be seen beautifully. So if you are able to hang the pot you put your Phal in, you'll have a much more beautiful, natural looking plant.
