How do I unlock the other boost rush levels as there are yellow boxes where I assume that other level packs should go. Anyone know how to get them?

You need to progress in the main games levels. When you complete enough of them a pack will be unlocked.
If you have completed all the levels, then you have everything.
They were going to do Boost Rush DLC, but they decided to do 82 Luigi-themed levels instead (New Super Luigi U) which cannot be played in Boost Rush mode.
