You can always favorite those really important tweets, or even resort to printing them in a compendium by Tweetbook.com. Some of my earliest tweets in a book form that I can go back and reflect on.
I agree that Twitter can do a better job of allowing us to search tweets by topic, but that's a 3rd party app waiting to happen. In the meantime, take a screen shot and post on your web or in flickr.
