As far as changes to the program, I found doing 5x5 deadlifts to be excessive in the novice version (completely drained me) and ramp-up 1x5 DLs worked better (a la Rippetoe/SS). If you still need more DL volume for whatever reason, I've lately tacked on 5x10 on the last day after the other exercises with 30-50% 1RM weight (a la Wendler/531's Boring But Big). Also needed to add extra arm work. Calves were a lagging issue for me BUT the sheer amount of squats made them come up naturally. Otherwise, this is perfect. Stick to this protocol with adequate rest, good form and a slight caloric surplus and you'll be somewhere strong in no time.
