My preferred way of doing PS fluid is to go buy a turkey baster, and just suck the fluid out of the reservoir and replace with new.. Do this every time you drive the car for say 5-6 drives and you should have mostly new fluid. The PS system only holds about 1-2 qts so you won't go through a lot fluid doing it this way. I've done this on other cars and very DIY friendly.

I'd ditch the K/N personally.. Plenty to read on that.

If you're changing the clutch fluid, remove the CDV while you're in there.

Diff, tranny, brake, and coolant fluid are good to do as well..

You should have done a Service II, which would include spark plugs.. At service II you should check the valves and adjust as necessary.
