what are the dimensions? This seems to be a bit large

There are (2) dimensions. Inner seal is a 3 inch diameter seal, which sits inside the basket. The second dimension is the overall "lip" which seals the inner seal of the basket; 3 1/4 inch diameter.

why can this plug not be shipped to a California address?

I ship to California addresses. I live in California

Does this stopper fit down into the drain, or at the top of the drain so that it sticks out into the basin of the sink?

Inner flange diameter - 3 1/8". Outer diameter - barely greater than 3 1/4" (not a full 3 5/16"). It sticks up into the basin of my sink, and barely provides a seal so that the most minor bump to it results in a leak. The inner flange rests within the drain, but the out flange keeps it from resting down inside the drain.

Is this easier to pull out than the plastic stopper?

I have no problem pulling out the InSinkErator STP-SS what-so-ever. If you are having a problem breaking the suction, you can simply open drain function with this stopper.
