David covered things pretty thoroughly, but I'll add some:

Some things the pet store got wrong...BP's rarely get to six feet. It's possible if it's a female, but even females rarely reach that length. Males are much shorter. Also...if kept well, they live much longer than 10 years....try more like 30-40!! It's a lifetime commitment!

Good for you, that you care enough to seek out the proper information and take advice on how to best care for your animal. Too many people don't.

If you're like many other first-time bp owners, I'm sure many more questions will pop up. Please feel free to ask them here. There's no such thing as a dumb question (except the one that isn't asked!) and we enjoy being able to help out.
