At one, I would hardly expect her to sit down at specific times and listen to songs and stories. Some kids love it, but so many of them don't have the attention.
When it comes to her testing you, I think you just have to ride it out. Set some clear expectations and enforce them. She will pick up pretty quickly that you have certain rules in your house. I think she probably is testing her limits, to see how far you will let her go. When she is doing something the first couple times, redirect her attention to another toy or activity. When she starts to do it just to piss you off, lol (you can tell, when they look at you with the devil in their eyes!) then implement whichever method of discipline you use.
