Hi guys!

So I bought this orchid a couple of weeks ago that looked fairly healthy on the surface (actually one of the very few plants I didn't get on clearance). She was potted in soil and some peaty type mixture with only a little bark, so I decided to repot  immediately despite the flowers. I removed all the previous substrate and the plug, potted it into a mixture of mainly bark with some leca here and there, let her stand in water for about 30 min, drained, and left her be. She had quite a few broken roots but I left them in hopes that they might still be functional, but cut off the obviously dead ones. A week later she was looking dry and droopy so I watered again (by letting her stand in water for 30 min or so), but she didn't become less droopy. I then took her out of the pot again to look at the roots and all the broken pieces that I left were either fully dry and dead or fully rotten. She's now left with only two pieces of root you can see at the top of the moss, and nothing else. I looked up some ways of helping an orchid grow new roots, and decided to put her into this makeshift system you can see in the picture:
Outer pot is just a cut up water bottle, followed by some leca and water to raise humidity. The inner pot is just a regular plant pot with a raised part (air column?) in the middle. There's some leca at the bottom of the inner pot as well. The orchid stem sits on the raised part of the pot, no contact with moss/leca or water. I put some moss around the inner pot and let the two remaining roots sit on top of it, making sure I left the stem not in contact with the moss to have humidity and airflow, but not to have it soaking all the time. Orchid is under a grow light (and has been this entire time). The idea is to add water incrementally and have the leca do its wicking magic to keep the moss moist. I'm aiming to keep the water topped up to the level of the rings on inner pot (not pictured because we're having issues with our heating that'll only be fixed today, so I didn't want her standing in cold water overnight. The moss is moist.

Now onto the questions:
1. Everything I know about plants tells me to cut off the flowers in this situation (despite the fact that some blooms haven't even opened yet), in an effort to conserve the plants energy and spend it on roots rather than flowers. But I also see some very conflicting advice on cutting off orchid flower spikes while in bloom. I should cut them off, right?

2. Do you think my setup offers her the best chance of success? Is there anything you would recommend for me to do differently? 

Thank you all.

Please help me help this beautiful orchid :(
