Supposedly you can unlock bikes/karts and Bowser Jr. by winning the 50cc, 100cc, or 150cc Retro Grand Prix Cups, but how do you unlock them to begin with?I got 1st place trophies in the 50cc, 100cc, and 150cc races but it unlocked the Mirror Cup - not the "Retro" Grand Prix Cups?.

Shell, Banana, Leaf, and Lightning cups are all retro cups. They are tracks taken from the older games.
