If you run one cycle without rows or chinups, it won't kill you.
Deads will isometrically work the back, but that doesn't tend to be enough for more advanced lifters.
Power cleans will definitely give you development. Honestly, I say, go with the routine AS IS before you mess with it. That goes for basically any of these routines we've got - it'll definitely work well for you. Give it a month or two, see if you like the results. If you feel the need, throw in some chinups and/or rows for a few higher-repped sets once or twice a week.
