Does the coupe come with a Chin Spoiler as standard equipment?

a splitter? Maybe on the later sport tuned packages, but im pretty sure they do not.

Never, the front lip spoiler was an option. The 06 and maybe 07 coupes had a different front bumper that came with the sport package that looked more like it had a spoiler, but it didn't.

Yup... optional factory lip is quite hard to find as well.
