So if you just want to set the play position back to the beginning, all you have to do is this:

MediaPlayer.PlayPosition.Subtract(MediaPlayer.PlayPosition);

Here is another change:

Beta:
MediaPlayer.MovePrevious();
MediaPlayer.MoveNext();

CTP:
MediaPlayer.Queue.MovePrevious();
MediaPlayer.Queue.MoveNext();

TimeSpan structs are immutable, so the Subtract function is actually returning a new TimeSpan with the modified result. Flipflopping the track should work though (not sure about the result if it's playing the first or last tracks)
