Congrats on getting into NC State, my fathers Alma-matter and my school of preference (sadly out of state tuition and having a free ride to Old Dominion made it an easy call, but hey, it feels good to have no student loans!)
Based on my own undergrad as a Computer Engineer, none of these books will come into play until late Junior/Senior year.
I recommend focusing more on circuit theory and micro-electronics (assuming you feel confident in your ability to learn the math up to differential equations). I'll have to go home to remember which books I used, but you'll want to lookup which ones they will use for the actual classes(circuit theory will probably be sophomore year).
If you still insist on studying some of the deeper stuff, one of the good Hennessy/Patterson books I've used is
Computer Architecture:A Quantitative Approach(However, I might not have used this until I was taking grad courses, since I took a bunch of those while a senior)
EDIT: Seems Plasmasnake beat me to the Quantitative Approach while I was searching for those Circuit Theory books.
Is it a combined Computer & Electrical Engineering degree at NCSU? We had seperate degrees and I missed gettting a dual degree in electrical by 12 credit hours (didn't find out until my final year and I opted to get a jump start on my masters so I was done in 1 year, still got a minor in electrical engineering)
