I haven't been keeping up with this thread, so I apologize if this has already been mentioned.
If you have a Mario Galaxy save file, Rosalina will be immediately unlocked in Mario Kart Wii. If you don't have a save file, you'll unlock her by earning at least one star rank for all Mirror Mode Retro-Cups. Despite her small frame, she is in the Large class.
And here are the returning tracks for the Retro-Cups.
