I'm not sure about the 4wheel steering, you'd have to get the necessary parts. You might have to find a way to mount the rear servo. I can't remember if the kit has a axle mounted servo option.

I have not experienced this myself, so I can't really comment on this. The CVDs on this kit looked pretty strong to me though.

The stock motor is a 550 can size. So 27T is enough. If you really wanted to you can move to a 21T 550 can motor.

I'm sure you can mout other body shells, I've seen some other people do it.

I don't like putting extra rotational mass besides the wheels. If you do... I'd probably put them on all 4.
