Since the 4/3 sensor gathers so much less light than FF at the same f-stop, how many stops should I overexpose by on a FF body if I plan to crop in post?

On any format, when shooting in raw, you should expose to get the most light on the sensor consistent with desired DOF and lack of motion blur, so long as you don't blow out highlights in which you wish to preserve detail.

Since the 35-100/2.8 is so clearly different in dof from the 70-200/2.8, why not compare it to the 24-70/2.8, which is a similar range of focal lengths and therefore has similar dof?

Because it's more useful to compare equipment that produces a comparable result. In this case, you'd want pictures taken from the same position with the same angle of view producing the same DOF with similar noise.

The 35-100 and the 24-70 will result in much different angles of view (35 compared to 24, 100 compared to 70 and intermediate values).
