So, I gather you have the garage space to park it in, and room to stash the big pieces nearby ?

And, no other projects with which to confuse the parts....?
Because you are going to take your time doing this...

and nobody's memory is perfect

, and no manual tells it all

... Before you even start, set up a "cataloging system" for your parts/bolts/fasteners/brackets, get:
Heavy duty ziplocks, wire ties and paper/cardboard tags
Permanent marking pens, pieces of paper and a camera.
Before and/or during taking each thing off (well maybe not the hood, that's pretty simple) take a picture. If some point in each process is complex, take a shot of that. Take some overall shots too, underhood wiring, dash.... ... .. .
Print/label the pictures, and put them in a ziplock attached to the ziplock holding the parts/bolts from that part. If you have an idea that might make putting it back together ("lesson learned") make a note of it and put it in the bag with the picture. Attach these ziplocks to, or put in a box with, the parts and bolts/fasteners/brackets for that part.
If it's convenient, put each bolt back in the hole it came out of, if not, bag and label them separately for each part or set of parts. Don't lump too many parts/bolts together, or else you'll be wondering which bolt goes where... If some bolts on a piece are different lengths, make a note of which length goes where.
I know this sounds a bit "dumb", but along about the time you're saying "Now whereinthehell...

" for the third or fourth time, you'll regret not having done it.
Then, to me, the order would be:
The "junk" as you say must go, then remove the seat(s) and carpet, and brush/vacuum/clean.
Big parts next: hood, tailgate, bumpers, fenders, grille, radiator, inner fenders and radiator mounts, gas tank, bed...
