Copper Queen Questions for a total newbie

[PDXguy]

Hi all! Go easy on me - I'm just a guy who bought a plant and wants to make sure it grows to be happy and healthy. I don't have a green thumb, but I follow instructions and pay attention to my plants, so every bit of info really helps.

The tag on the plant I bought said:
Orchid: Blc. Copper Queen

What does "Blc." mean?
How do I care for my plant?
How often will it flower, and how long will the flowers last?

It's beautiful! It stands maybe 15 inches tall and has two orange/yellow flowers (is that what you call them?) and of course long, thick green leaves.

It came in a small container with lava rocks, and I believe I'm supposed to run water through the rocks once a week.

I have that container sitting in a tall vase where it can't reach the bottom, and I have some water sitting below the rocks at the base of the vase (the container has slits at the bottom). The plant is sitting in a north-facing window (ie, no direct sun, but lots of light. All of my windows face north, so I hope that works.)

Am I off to a good start?
What do I need to know?

Thanks so much!
