Turn off the breaker before you work on anything, if you aren't 100% positive that you've got the right breaker, turn off the main breaker, if you still aren't sure, just stop. Always do a pull test after joining two wires and apply electrical tape liberally. Be wary of aluminum wiring and even more so for knob and tube if you ever see it. You'll eventually hit a point where you realize you can get creative with the materials you use and the way you do things, don't do that. This is also about the time you'll start to feel confident in your skills as an electrician, this is when you're going to skip something basic and electrocute yourself, it will probably be minor and you'll be sore for a week and feel 10 years older. Sometimes though it's not minor, it's an electrician meme, but we all have the "Remember kids, Electricity will kill you" sticker.

If you remember all that, you're probably good to install the basement outlet, you'll probably have local building codes to adhere to, but they're usually not a major burden to comply with. For your chime, do you know if you have a doorbell transformer at all (and are you sure it's getting power if so) or where the wires on your doorbell go to?
