Bonding hot and cold lines?

I'm assuming the black wire in the first picture is where the water line into the house is grounded. But the second picture shows there's no grounding or bonding going on at the water heater, so since it's a simple thing (whether it's required by code/not required by code/helps/doesn't help), I'm thinking to add the bonding wire. Question is really just to confirm how to do this....I just connect the cold in line to the hot out line with clamps and a #6 wire? Is that it?

Yes sir..... that's all there is to it. Two clamps and approx 18" of wire.

I'm glad you posted a picture of your water heater.
As far as I know..... that flue flex line is not an approved venting method.
Interesting..... usually the furnace is the upper connection in a chimney/stack.

Should the clamps also be made of copper? In videos/pictures I see, it looks like the clamps are steel. Could that not cause galvanic corrosion?

As for the flex venting, I see where if it's the correct type (not dryer vent), it's apparently permissible. But I guess rigid would be preferable for better airflow.

The clamp shown in your picture is aluminum. That is the most common clamp you'll find.
Copper is too soft.

I have never seen flex line on a water heater or furnace before so it stuck out.
