Do all years and models of the HHR have a timing chain? Do some have a belt? How would I know which mine has? I know this is a little more dumb than the majority of things I post here, but I honestly don't know and was looking for some help. Thanks.

All have chains. Since its a ecotec it's a chain driven system. Doing timing is easy, just a lot of junk in the way to do it.

^ That is correct.

Thank you guys. So the chain will eventually need to be replaced? Any idea as to what mileage it would need to be done at?

I believe it's supposed to last for the life of the engine.

I had to do a timing belt at around 100K mi. on my last car, which had an interference engine. That was one of those jobs where no beer was consumed until AFTER I made sure the valves and pistons were not in conflict...
