Got my Catasetum today, now what?

[Dr. Dave 4u]

I seem to be lucky to have received a healthy looking? I think?
Catasetum from Sunset Valley Orchids today in the mail.

What do I do with this BAD BOY now?!!

Never had one before so what are my options with it while its in dormancy? Can I still pot it up without watering it?
Store it for now? Do i remove all those dead roots or do you leave them so when you pot it up the hold it in place?

Keep it out of eastern window sun? Is indirect light good or bad when dormant?

When do they come out and do you tell by beginnings of leaf growth?

Thanks for the help
