help with my phalaenopsis

[failingflopsis]

From your pictures you have a healthy orchid! The flower stem will turn brown like yours did after the plant has finished blooming. When the plant is ready to bloom again it will sent up another spike, in other words the old stem will never do anything again. Those are normal healthy roots coming out the side. When was the last time it was repotted? Generally phals like to be repotted every couple of years.
