Congratulations on your Phals and lights!! How exciting for you!
Everything Mike and Kevin said above - Ditto.
I always, always repot new Phals even if they are blooming because I have lost too many that had root rot starting before I got them. This goes double if you bought them from Lowe's because they are not orchid growers. Being a beginner and having them in two different mediums will be confusing to you and at least one of them will suffer.
I love the skewer method and still use it. It is invaluable when trying out a new medium, drying lights or moving plants around. Just pick one (as you have) and try it. You can grow an orchid in most anything if you adjust your watering habits to it.
I have my blooming Phals downstairs away from their lights for months at a time so I can enjoy the blooms. You will be fine until you get your lights set up, in fact most people start out by growing them on a windowsill.
Enjoy them! You have started a wonderful new hobby!
