For fuel: first, make sure your warming up. Engine should be operating in the 205-210 range. If anyone has put a low temp thermostat in, the engine's running "open loop" all the time. Also check the temp sensor. If it's failed, it can also cause the same problem.
Check/change your O2 sensors. As the sensor goes bad, it will work well enough to keep from throwing a code, but gives a false "lean" reading, and the computer tosses more fuel into the mix.
Power steering: Is it leaving a puddle? If not, just watch the level and leave it alone. Deal with it when it starts to drip. You might want to clean the area really well and confirm the leak location. It might just be a loose fitting or pin-hole in a hose.

My other car is also a Jeep,.. and so is the other one,.. and that one too. How many do you own before it's "a herd" ?
