1) Evolution always has results that will be considered poor design. Every time an evolved "design" becomes obsolete with respect to its surroundings, then it becomes a poor adaptation, at which point it must evolve again. But because this process is continuous, we consider this whole continuous process as evolution. As time increases, evolution will always force something to adjust to its environment and become perfect with it, therefore evolution as a whole can be considered absolute and perfect.
2) Evolution as a whole is absolute, so obviously it's not luck. The adaptations and changes before the perfect "design" arrives are determined by luck as you say.
When I say design I just mean the product of some systematic process. Planning is systematic, but so is evolution.
