Beginner Gardening: Questions about my Fittonia, 0 by mandapandabear

This Red Angel is sold by Exotic Angel plants. I bought it in July and It has grown very well. It even started to grow little flowers :)

-The leaves' veins started a very pretty red when I bought it but since it grew to about four inches I noticed they've turned hot to pale pink. Is that typical?
-All of the flower stems have fallen off. Is that a normal thing and will they grow back soon? I just assume that the flowers shed themselves with the weather changes. The plant overall looks awesome but I miss the flowers. Websites don't mention the flowers at all so here I am lol.
-I started this plant in a regular potting soil but read that they do better in African Violet soil. Should I go ahead and transplant? Or will the autumn season effect that?
-The Exotic angel tag says its a low light/high humidity plant so I thought it would do great in the bathroom (with one small east-facing window). Should I move it elsewhere? I figured it would benefit from the steam of the showers. I mist it daily and water it about once a week. I've fertilized it once in three months with a Miracle Gro plant food spike.

Sorry for all the questions but I am very curious about this beautiful plant and I want to care for it properly! The leaves were becoming sunburned and brittle when I sat it near a window so I've had to do a lot of nursing with it. Misting and the move seemed to have helped but I'm concerned about the flowers.
