Like I stated before, other members have tackled all the projects you have mentioned. Use the search function or stroll through the 2000-2006 interior section. There's way too much information on subjects like painting the interior plastics, changing the headliner to a darker shade, etc to be brought up and re-discussed in your build thread. These things have been discussed to death, attempted, failed, succeeded, etc. However if you decide to jump in without doing research, prepare to not only most likely make the same mistakes but be called out for doing so. This forum is here so people don't have to make the same mistakes over and over and when it happens anyway, it's hard to watch. Take your time, research the best way to do it, and reap the rewards of others failures. I wish you the best.
