It combines control of steering and acceleration
During acceleration? I'm not sure. But when both idling and acceleration the engine's combustion can cause a lot of vibration in the steering wheel if you are in an older vehicle.
If you mean changing from left to right or vice versa, you need to obtain the steering rack that is made for the vehicle in the left or right configuration you want. The dash will have to either completely removed and replaced or modified by a very good fabricator. It is not an easy, bolt on job. Everything--EVERYTHING has to be the complete opposite.
you should take your car to a mechanic.
It is supposed to turn completely around. But if you mean it just keeps turning with no stops then you have a broken steering part of some sort. Possibly the steering shaft u-joint is broken.
No, Kia power steering fluid is not exchangeable with its transmission fluid. These are two completely different fluids mean for completely different part of the car.
It could be that your tierods are completely gone or the play is in the steering box .I have heard that there is a adjusting screw on the steering box to help with the play , but not sure .

Check for a broken motor or transmission mount
