Vcc is commonly called "enroute climb speed", and it's always faster than Vy. Unless a steep climb is required to avoid terrain or to fly a departure procedure, cruise climb speeds allow you to fly faster, with a relatively small loss of climb performance.
Carrying extra airspeed on final approach, and flying faster than the manufacturer recommends for your weight, usually makes it more difficult to land.
When you bank while maintaining altitude, your stall speed increases. It's something that you need to be aware of, especially when you're in the traffic pattern. So why does stall speed increase when you start rolling left or right?
The first question you need to answer in a power-off landing scenario is this: do you want to maximize the distance you can glide, or do you want to maximize the amount of time you can stay aloft?
