Fluid replacement and maintenance for Camaro SS A8

I own a Camaro SS A8, which is soon reaching 100,000 km (~60,000 miles). I've been using the car for the past year (~18,000 km), and I've only changed the engine oil once. Which fluids need to be replaced at the next service? And overall, what and how often should be serviced to ensure the car lives a long and trouble-free life?

P.S.: This is my first car, so I'm a bit unfamiliar with service matters, so I would appreciate any recommendations.

Thanks!
