There are quite a few threags on this if you search. The short answer is that there is not a concensus ont he order but from what I picked up, the out panels that alignment critical are where I started. The main take away is measure, measure and measure again, Every part, every angle. Take pictures and mark the measurements on them if you can. Brace the tub well so nothing moves when you start taking structural parts like pillars and posts out so you have reference. There are a lot of pictures that show bracing on here so you can get the idea. I started mine with removing inner/outer rockers, pillars and posts. Then quarters, front clip and floors will be last. I cant tell you that is the best way but it is working so far for me.
