The only thing I'd add is if I remember correctly, the Graffeo book is weak in: electronics, econ, and reliability.
For econ, I worked practice problems with just the FE reference material and I printed several interest tables.
Electronics: I used my book from college. Which, quite frankly, I'd rather slam my head in a sliding glass door than read that piece of **** of a book ever again.
Reliability: well, that happens to be my day job and I took a really good reliability course which had a lot of great reference material.
