This is the diagram on my instructions.



And this is what my wall looks like after removing the old light switch



My two questions are.

1. Will I need to create "pigtails" from that group of both the white and the ground wires rather than picking a single white or ground wire to connect.

2. I'm pretty sure the top black wire is the single pole a wire and the bottom black is the com (common?) wire. Does this sound right? I don't have a tool to measure "hot" wires.
