None of the older Pokemon have Pre-evolutions or evolution in Black and White, including Lucario.
Not the way you think. Pokemon Diamond and Pokemon White can not directly trade with each other. Once you have defeated the main storyline, you gain access to new areas. Between Nimbasu city and White forest there is a small building. This is where you can transfer Pokemon form Diamond to White/Black. You need a second DS to do this.
