I am sorry I was unable to take picture because my hands were oily and I actually did not think what i done today was gonna work so I was improvising as I went along, but it did work very well, I was able to flush the entire old fluid out.

I believe it is so simple that no pictures are needed, I will also put maximum information possible.

1) remove the inlet air duct to clear the way and have a better access to the fluid reservoir.
) you should see a hose that is connected to a metal tube with a clamp and going to the oil reservoir, this metal tube is coming from the oil cooler at the radiator, if you are standing in front of the car then it will be on your left side. This is the line that brings the cooled fluid back to the reservoir and this is the line that we will be working on. Please do not touch the other hose that comes from below the reservoir and goes straight to the pump.
3) put a big piece of rag underneath this line, and with a pliers remove the clamp, disconnect the hose from the metal tube and face it up to stop the spill immediately. Plug it off with anything you see appropriate, I used the soft side of a 10 mm drill pit.
4) find a 1 meter length of hose (I used a water tube) and connect it to the metal tube and clamp it in place, run the other end through to underneath the car to a containment to receive the old fluid.
5) remove the cap, place a funnel and get ready with at least 1.5 liters of fresh fluid.
6) now because the oil circulates too fast in the system, you won't be able to catch up, the fluid will be sucked quickly by the pump from the reservoir before you will be able to compensate, so you will have to do this in stages.
7) start the engine for no more than 2 seconds then turn it off immediately, you will see that the reservoir is almost empty and the old nasty oil started coming out to the containment.
8) fill the reservoir all the way up to the neck, and then start the engine for two more seconds then shut it off, repeat this step till you see clean and sparkling oil coming to the containment.
9) remove the water tube, unplug and put the hose back on to the metal tube and clamp it in place, remove the rag and clean the place up.
10) make sure that the fluid level is between hot min and hot max, put the cap back on, reinstall the inlet air duct.
11) start the engine, turn the steering wheel from side to side several times, check the fluid level once more and add if needed, and you are done.

I did not notice any improvement even though I expected some, but i guess this is a preventive maintenance which helps in maintaining a good performance and avoiding problems rather than producing improvement.

As for the PS fluid, and whether it needs to be changed or not (and how often), that i do not know and i was not able to locate it in the service manual, the old fluid looked really bad and I just feel comfortable having fresh fluid instead.
