VERY logical!

Get accustomed to spaghetti code, you'll be less stressed! LOL

The Build Manual can help guide some of this too. You will also need to be cognizant of sequence, especially when you start riveting panels and installing for the final build.

I started keeping a Punch List of things I wanted to do and update it FREQUENTLY.
My first page was things I wanted to do that weekend or within the next week or so (immediate term items). I checked them off, or added to them after every build session and kept a printed copy on my desk at work so I could jot down notes as they popped into my head or on the drive into the office.
and the following pages (yes 3 or 4 pages of items) were things I thought of that I wanted to document so I didn't forget or remember after a point of no-return. These items were broken down by areas like you identified: engine, interior, wheels, wiring, trunk, exterior, and NEED to PURCHASE, etc.
