Hi Mike,
Welcome. It's hard to know where to start w/ your first question -- this 4 part discussion has covered so much ground. Maybe scan through the thread and read the parts that strike your fancy, to get you started.
As for the Memory Supercharger, it's a paraliminal tape put out by Learning Strategies. It's designed to greatly strengthen your recall abilities. I've had very good results with it myself and others here have reported strong results, too. Some memories that came back to me were almost as clear as real-life after several days of listening. This was not previously the norm for me. Here's some links that should be self-explanatory and show you what some people have experienced with it.

Brian,
Yeah -- rebounding is great! I'm amazed it's not more widely done, considering the health benefits. It was considered a fad once when cheap quality units were widely available in sporting goods stores. Maybe people dismiss it as a thing of the past like they do with the hula hoop. Maybe it doesn't quite have the marketing 'sex appeal' of the Nordic Track, Tae Bo, etc.
