I would just flush and change every fluid you can access reasonably. I bought a 2000 GTS and I'm still in the process of flushing fluids (it's winter time, so it's hard to find good days to do it, lol).
You should definitely flush your power steering asap.
Coolant is a big one - make sure it's pink/red. I picked up a jug from the dealership, then hopped on Amazon to order the same thing but cheaper.
You'll want to change your transmission fluid too, especially if it's manual.
I would also flush your brake fluid too, but if it's working fine atm, it's probably not super high priority.
For mine, I've changed the oil (I actually used a chemical flusher), flushed the power steering (it was nasty), and changed the manual transmission fluid. I still need to do coolant and brakes.
I also changed my battery to something new for peace of mind.
