What size ring connector is needed to attach wire to terminals?

They are #8 as described in the description. Hard to find #8 rings in heat shrink connectors. #10 worked just fine for the terms and it seems all manufacturers sell this size.

Can I run +/- from batt to 100 amp breaker then +/- to fuse box so I can kill power to fuse box?

Yes you can. The fuse box will be powered off breaker. I used a toggle switch panel instead of a main breaker.

Product page says this can handle 100 amps per block, does that mean 100 amps on the left 6, and another 100 on the right?

No, it means 100a peak draw for the entire block...30a peak per circuit. The main positive in should be fused at 125 per the specs from BlueSea.

Does this block come with a positive and a negative bus? I don't want to have to daisy chain the positive lead to each lead on the panel...

Yes, it does indeed come with both a positive (fused) bus and a negative bus. Very nice unit, as with all Blue Sea products. I would and have bought again after purchasing mine.
