Well,my preference,if you have the room is to take off the hood and the deck lid and support them on horses so you can still paint them at the same time.I start from inside the engine bay and work my way out.right fender,door,door jamb,rocker,1/4 panel,right half of roof,trunk jamb,left half of roof follow down to finish left 1/4 panel,door, rocker,fender.Don't forget to hit any valance panels(front or rear)in the process.Seeing how the hood and trunk are detatched you can paint them anytime in the process.Don't forget all your nooks and crannies.Once you get that thing outside in the sun it will let you know if you missed anything.I prefer to paint my cars as a whole.Gives a nice uniform look and eliminates overspray.If you try to paint pieces here and there sometimes you will end up with color variation.But it's usually when using metallics and a whole bunch of blah blah blah.You get the point.I say do it all at once.When your done,your done!Oh forgot to mention.If you take the deck lid and hood off of course you wil lhave to spray the underneath ahead of time.Definitely easier if you don't have to open and close your hood and deck lid all the time,also better acess(nooks and crannies).Well hope this helps.Hope ya didn't fall asleep.
