The service manual is a good resource to know the sequence. I did it this way:
a.- Remove the sun visors (2 screws for each)
b.- Remove mirror from the base glued to the glass (pray then pull straight down)
c.- Remove the plastic over the interior lights (popsicle stick works)
d.- Remove the 2 screws holding the interior light assembly on
e.- Unplug the 2 wire conections (interior lights and garage door opener)
f.- Remove the side pillars (I inserted 2 wooden kitchen utensils from the top and pulled rather hard towards the interior, they snap off)
g.- Pull the rear sail trim panels down until one plastic clip lets loose
h.- Pull the center of the headliner push pin down (by the rear glass) and remove the trim pin
i.- Move the seats all the way front and recline them all the way back
j.- Gently pull on the perimeter and it will come down
k.- I don't know how I got it out the passenger door but thats where it comes out, take your time so you don't damage the corners. It's real tight and won't come out if the angle isn't just right. You can't come out diagonally or backwards or any other way except the installed orientation, front slightly diagonally down. Good luck!
l.- I forgot to remove the garage door opener but it was unplugged and come out with the headliner.

Everyone feel free to add tips and hints.
