No.
Very few aftermarket ones will, Sony used to make a model that would in the 1990's but it may not be available anymore. Only factory stereos from cars with steering wheel controls have the plug on the back to accept the wiring from the steering wheel controls.
yes. there are aftermarket brands that offer remote capability but it has limitations. if you really like the remote controls you might want to look into an original equipment upgrade to gain a CD player or multi CD changer that was made for your car and retain the steering wheel controls, you can usually pick one up at a junk jard.
More than likely the answer is no.
Crutchfield sells a kit that allows you to install a single din aftermarket stereo where the pocket under the A/C controls are located.

the special wiring harness that you purchased is used for accessories such as your radio controls in the steering wheel, door chimes, and the beep for when your lights are still on. Other than that, if you have the harness itself hooked up to the speakers RIGHT and the CD player RIGHT, then you should have no problems and no worries.

You can plug in the nunchuck to control steering differently or you could use the gamecube controller which is the same controls as the ds.
Almost definately. I had the radio cassette in my wifes 02 Clio replaced by a Renault CD player and it worked with the steering wheel controls. Not sure about the procedure (we had it done at the dealership we bought the car from as an add in when we bought it) so don't know what if anything else they had to do.
If the face plate of the original factory radio is Oval, like the 1997 escort, you can get a new radio faceplate that will accept a standard aftermarket radio from crutchfield. Mine cost $49 back in 1997. It even takes the original A/C and rear defroster controls.
no, a factory CD player can be used in a vehicle that has subwoofers attached. as long as the factory CD player in the vehicle has treble, bass, and subwoofer controls on it, it will be fine. if not, an aftermarket CD player will be the solution. with subwoofers, you need to control the amount of power that are ran through them. the amplifier is a control, but if not set correctly on the CD player, you could blow your subwoofers.
