Don't have any experience with power steeling fluid flush.
I would do coolant flush for my car every other year. It can be done for about $70.
For transmission fluid, dealer recommend changing it every 30 miles, but you don't have to. Check the trnasmission fluid color (by pull out fluid level stick), if the color is still pink, you can still use it. If it turns brown, have it changed.
If the brake pads are worn, you need have them changed. Changing front brake pads should cost about $70-90 at brake shops like CarX. You don't have to do that at dealer.
Fuel injection service is totally a scam. This is considered not useful. Don't do it. If you want, you can do it yourself. Pour a bottle gumout fuel injection cleaning solution (you can buy it from any autopart store) into the gas tank before your next gas fill up. That's it.
