Newly arrived orchids. What should I do?

[Zindaginha]

Hi! I am totally, completely new at orchids.

I just opened a package with the following:

1. mounted eria pannea
2. mounted sophronitis cernua
3. Potted (or just bareroot, really, since no medium at all) dendrobium reflexitepalum

They all seem healthy and minimally disprupted by their travels. Except that the sophonitis' roots seem slightly flattened (still white, though, so maybe that's just the shape or something?).

These are my questions, since I want to make sure that I start things off right:

1. Sophronitis like light, so should I just stick them with my light-loving broms and carnivores by the east-facing window with the supplemental T5 light? (My nepenthes set-up, sincd they are the most demanding. The rest of the plants just go along) Or would this be shocking after being in a box for two days?

2. Sophronitis don't do winter dormancy, so I should go ahead and soak this guy right away and get it started on a regular watering schedule? Or should I gradually strt doing this?

3. What should I do to rpepare the Dendro for dormancy and should I still go ahead and give it a drink right now? It is large with dark, firm leaves so doen't look anywhere near dormancy.

4. Eria Pannea grows everywhere for its natural habitat--so does it need a dormancy?

Basically, the dormancy thing is throwing me off. I'm familiar with how to deal with it in succulents and know what to look for in carnivores, so I wasn't even thinking about it, but now I'm completely panicking.

Gah! Help, please!

And thanks!

PS: panic aside, I am sooooooo excited and wowed by these things!
