Okay, there is one thing you MUST do before you ask any more questions - go buy the repair manual for your vehicle. Most auto parts stores carry repair manuals - Chilton or Haynes for example- and buy yourself the one for your vehicle. The Haynes one runs between 15 and 20 bucks and is about an inch or so thick. Take it home and flip through it - removal and installation of parts and trims - like the dash - is usually covered in there. And that money you just spent for the book will definitely be a good buy for the help you'll get from it. The repair book t will answer a lot of questions and at the very least, help you be a bit more informed when you go in for service or repairs.
