I only checked the cells that I added today, and I am not sure I checked all of the cells I added earlier. One of headway cells I tried to add today was discharged to 0.42v, I'll try to charge it up again but with v that low I am skeptical about its chances - I want to make sure it is the only one, but I am not ready to tear the pack down to do so. Two cells stripped their screws holes pretty easy, I figure I'll use them as end cells later with a slightly larger screw.

Yes, you can measure the potential (voltage) across any individual cell, regardless of how it is connected to other cells. Just jump in with a multimeter.
You can also charge or discharge any individual cell in the same fashion, while connected to the others. The circuit (say the multi-meter with probes on each end of one cell) is only 'closed' around that cell, so that's all it sees.

Curious on the charger settings, though. You mentioned you are charging each block of cells to 3.3V, which is the nominal voltage for LiFePO4 cells, but to get a full charge, you need to go to at least 3.65V per cell and then let the current taper off.

What is the finale volts and Ah are you going to use and what speed and range do you hope to get?
