Have I conquered low light D7000 photography?

I set the D7000 to P and set ISO to 2000. This allows me to get these results all the time. I can set then speed to 1/50s (which I feel comfortable with), f5 which allows for easy focusing. These are with a 50mm AF-S 1.4. Wb set to fluorescent in my low light kitchen.
