If it's leaking, you'll have an empty co2 tank in the morning, so check for leaks first! You can use soapy water on the posts and lid or dunk it in the bathtub.
I leave my co2 connected all the time- that's what carbonates the soda or beer. Force carbonation forces co2 into the solution. You have to have it connected to co2 to do that.
