Just to further drive home the point these other guys are making- 5'8 154 pounds is skinny! The fact that this is still your weight after a year on a lifting program means you didn't eat enough, and hence the lack of progress. Despite your protestations, I don't think there is any way you were eating much more than 2500 calories per day over the last year.
There is an online SS wiki that lays out the program pretty well. Read that and get a start while you wait for your book.
I think 3 sets versus 5 sets will make a big difference for you in terms of workout-to-workout progress if you eat right.
Load your overhead press and bench 2.5 pounds at a time.
