Power steering fluid flush? Never changed it on any car I've owned, ever. As far as I understand it's just designer hydraulic fluid similar to transmission fluid, which will work fine. I'd check the oil level in the diff and fill as needed only, unless you've been racing regularly. Changing the brake fluid is easy enough to do yourself. If it's never been done before in 14 yrs. I'd do it. I don't know what a fuel induction service is. They're offering mostly needless service to give you piece of mind after planting seeds of doubt.
