I don't need the membranes (I have 10+ spares), can I just get the o-rings?

sorry. that is the only package we sell.

Where do the o rings go?

They go on to the pump handle diaphragm stem. If you ever lose suction it's most likely because one of these came off. Search for "medela hand pump o ring" images in your web browser to see a visual

What are the dimensions of the O-rings?

I don't know the exact measurements of the O-rings but I do know that if you are trying to replace a part for a Medela manual breast pump if it's perfectly.
