Hi Fiat,
Don't repot your Zygo. There are only 4 reasons to repot and your plant does not fit any of the reasons. If the plant gets too top heavy and wants to tip over, drop the plastic pot into a larger, heavier pot for stability.
You won't need to repot until at least next fall. Zygo's are tricky to repot as the roots are easily broken and damaged. You essentially have to reroot the plant every time you repot so wait.
The Phalaenopsis shouldn't need repotting either. The old bloom stock might re bud and bloom again for you in a couple months.
PS: Roots growing out of the pot is normal for orchids. They grow in trees so roots growing every which way is just what they do.
