Soggy Brown Roots-Just Bought a Phalaenopsis, Help!

[OzAbie]

Hello there! I just purchased three Phalaenopsis' that were on sale. One of them is great but the other two have really brown soggy roots. I can practically squeeze water out of them. I've had orchids before but always killed them and I am determind for these three to not meet the same fate. I brought them home and rinsed them off, cut off any black roots and just kind of set it in its pot for it to dry a little. Now I'm rushing to find information so I can keep them alive! The leaves and stalk are still ncie and green. One of them the leaves are a little wrinkly.

They came moss type stuff with some packing peanuts at the bottom.

Can anyone give me information? I've searched the site but a lot of it was over my head. I read mentionings of a bag system? But I dont know what this means. What can I do? Thank you so much for your time!

Here's a picture of one of them, the other looks just like it.
