Brandon,

Here is great review article that describes the progression of levels of processing.

Baddeley, A. (2012). Working memory: theories, models, and controversies. Annual review of psychology, 63, 1-29.

I don't know much of the contemporary applications of this model, but I'm personally interested in inhibitory control.  The act of retrieving information can render subsequent related items less accessible, also refereed to a Retrieval Induced Forgetting.  This is a popular topic now-a-days and has a nice Wikipedia page that might interest you.

This might be of interest as its quite a bit more recent than the 70s...
