I agree with both Matt and Jeff D. Go for a heavier program. You seem to have pretty good choices considering the knee thing. I would go for something along the lines of 5X5-6 reps (first two sets being progressively heavier warmups, the nex three sets being hard work sets). I would also go one step further and dumb it down a bit. Split it into two programs, alternating them, using basically the same eercises, with one exeption,include deadlifts and powercleans. They will get your lower body, and really shouldn't bother the knees that much in the way squatting will
A DL, BP, Row, then add in your arms
B Power clean, Lat pulldowns or chins, then add your arms. (The power clean is basically a light deadlift with an upright row to shoulders, then you press. kills a couple of birds with one move).
Also, cutting back on the number of eercises allow you to focus in and work harder o each, with heavier weight. Should be good for 4 weeks or so, then resume your program you have now.
