In reference to the sustain pedal, it may become a troublesome habit if you use it too often. My piano teacher once performed a Bach piece and used the pedal to make it sound smoother, but he was criticized by the judge because in Bach's time, there were no sustain pedals on pianos. Even some composers themselves, such as Grieg, demanded that the pedal only be used when indicated. I have a bad habit of using the una corda or "soft" pedal. This eventually left me with a slight inability to play softer without the pedal. This is not to say that you can't use any of the pedals on a piano, just be aware of why, how, and when they should be used.
