Welcome to the board!
You really can't replace the dash color in your YJ! Well OK You can But heres the deal! 91-95 YJ's Are back lit gauges, When chrysler changed the dash, they never changed the bulbs, so it was a very bright, so what they did is put blue sleaves over the bulbs. Know how you can buy thos blue sleaves at pep boys or Autozone to change the color of a bulb with out accually changing hte bulb, Well you got those factory! In theory, you can replace the bulbs with a new color, but 2 things,
1. I don't think they make a colored bulb that fits!
2. Why?? If you want your dash to look a bit different, you can get white face guages pretty inexpensive and look pretty good. Check it out

As for the Paddle handle, pretty easy. Remove the interior pannel by removing the pull strap, and window crank (to remove crank, pry the center out and there is a torx screw inside) Us a pannel puller and just pull the clips off. You can pull them by hand just be careful that you don't break too many. The top rear of the door is a removeable pannel held on with 5 screws, take that off.
Here is where it gets a bit tougher, unscrew the Bear Claw mechanism and there will be the back of the paddle handle. Two black torx screws hold it is, unscrew and disconnect the accuator rod from the white clip and your done. Put together in the opposite order!
