I'm a newbie myself so I may not be of much help. I'm sure our Forum friends will be able to help you.
I think I know who you purchase your orchids from, my first Ebay purchase were from the same vendor. The #'s and letter before the name is how they track/id their plants.
Make sure you soak them when they arrive, I'm sure they're gonna be thirsty, you can add SuperThrive to the water.
Goodluck
