Great tips, but wear a dust particle mask if you're going to blowtorch the fuzz, who knows what chemicals are in those deliver and toss woods

A used nail stash can be gold, especially on a late Sunday afternoon at the finishing line, when the shiny new packet has run out
or left you a few short to finish the job
If hidden nails are a concern, get a demolition type circular blade, they are designed for wood with the occassional nail.
The sparks and screech will let you know there was a nail there, and just keep sawing. Diablo makes them IIRC, maybe the other players too DeWalt, Makita, Milwaukee etc
Or if you need a new or second circular saw, Evolution make a slower rev speed circular saw that can plough through hell apparently, including metals, and the price is very fair for what you get.
I park tools on foam or cardboard/newspapers, not on fuzzy unknown wood.
I reckon if you're going to blowtorch the fuzz, may as well give a quickie coat or two of cheap paint to seal in any nasties
(enter the heavily discounted 15 litre bucket of returned mis-tint, from a paint retailer that wants it GONE)
...and don't forget the cheap castors with brakes, for that mobile workstation vibe that doesn't break the bank
