How can I puppy proof my home?

I am planning on bringing a 9 week old St. Bernard puppy sometime next week. I am not getting her yet, because I am still getting my house ready. I have a crate, toys, 2 bowls, a leash, collar, fenced in yard, brush and bed. Is there anything else I am forgetting? How should I “puppy proof” my home? My Bernard’s name will be Nyla in case anyone wanted to know 🙂
