I seem to remember in "Shadows of the Empire", the book between Ep.5&6, that Luke wore those clothes throughout the story. They were referred to as a simple black tunic and pants.In terms of symbolism, however, I tend to agree with the thought that they serve as a visual sign of maturity. The white showing his innocence and naivete. In ESB his clothes are dingier, showing the partial loss. By ROTJ, he has come to grips with the truth of his father's identity, gotten control of himself and the Force, and become a Jedi. But the Innocent Farm Boy would never be the same....

His saber was green because He had to make it in a special mini oven in Obi-Wan's house on Tatooine, according to the process in an old book he had found there. That would have been written by the Old Jedi Order and Jedi sabers were traditionally blue or green, while Sith were red. According to SOTE, Luke used the force to help make the molecular structure of the crystal, thus infusing it with his emotions. The color was a result of the passive calm emotions exuded by the light side of the Force. The Sith, conversely would infuse violent emotions, such as hate, thus creating the angry red glow their sabers are known for. Subsequent novels and games have their Jedi constructing sabers with natural stones, so the color is more random. Personally, I think it's better to have random color, since the saber is supposed to be an extension of the Jedi's personality, it shows that no two personalities are alike.

Maybe thats why Lucas had them being standardized, to illustrate the Jedi's stagnation. Perhaps he was trying to show that they were unable to see the dark side's advance because of a loss of individuality. Could that be part of Anakin's bringing "Balance to the Force"? Hmmm...
