If you convert a MP3 back to a .wav then re-encode at a higher rate, is it any better than the previously lower encoded rate,

No. It will be worse. Once you throw away the information, it is lost. And each time you go from .wav to .mp3 you are throwing away more information. If your original .wav file had 100% of the information, and you converted it to an .mp3 that, say, threw away 25%, when you went back to .wav you would only have 75% of what you had to begin with. Convert that to a higher-level .mp3, say one that kept 90% of the original information, you are still left with only about 2/3 of the original information.

You can't go home again. (Hmmm.... that would be a catchy title for a book, wouldn't it...)
