first repotting, teacup phal

[tedro]

Hi,
I have "teacup" Phalaenopsis.
It's in its orginal see thru small plastic cup, which sits inside a small vase as simply a holder, the cup has a wick out the bottom so a holder is necessary to remain upright.

First, I wish to ask: At what point do the roots start coming out and into the air just hanging out?
Does that happen naturally when the cup is too tiny? If so, should I not repot until they do?

I realize that I most likely will not repot until after blooming -- blooming finished, but i have a rare bonus spike out the single main spike... this bonus (and fasciated) spike is blooming now and has about 20 buds!
After this is all completely gone is most likely, if not sooner, when i repot. So, i want to start getting a handle on exactly what i'm going to do.
This little guy (my first orchid) is just awesome!
here's a photo album: orchid #1 - Google Photos

the last picture (should be last) is originally when i bought it, that image has a color filter (not same/real color).
