Tolumnia care help

[OrangeAugust]

Hello,
I'm not new to orchids- I have a lot of experience with phals and dendrobiums, but I went to the Orchid show at the NYBG this weekend and they were selling so many types of orchids I've never heard of. I bought a tolumnia, but now I need to know how to care for it. There's some stuff online, but it's always helpful to ask questions and get some answers from people who have experience.
So, it's in this tiiiiiiiny pot... the roots are sticking out all over the place, and it looks like there may be 2 or 3 pieces of bark in the pot that some of the roots are holding onto. So I'm not sure if I should be repotting it... or how to water it because almost all of the roots are exposed. I did read that it likes to dry off pretty quickly after it's watered. so I'm wondering if I can liberally spritz the roots in the pot with the spray bottle every day. In that case there's no water sitting around in the pot but the roots get a nice drink.
When should I consider repotting, or should the roots just be all over the place like this?

Also, right now it gets bright but indirect sunlight. Is that ok, or should it have any direct light?
