Wood working skills?
Pretty decent. Built a 5'x7' family table that looks phenomenal. Built a 50gal aquarium cabinet. Built various car sub boxes.

Any history in setting up PA? None

Soldering? Lots. Have a 1000W hot air rework station and occasionally repair amplifiers.

Electronics? Used to design switching PSUs, write firmware for microcontrollers, and design some controls boards, PCBs, etc.

Awesome, you can put some great ticks in boxes, and that will help...
Built:
DR 250: x 2 melded array, 2x CD horn, March 2012 plans.
T39's: 4 x 20" BP102 , 2 x 28" 3012lf.
WH8: x 3 with melded array.
Bunter's Audio and Lighting "like"s would be most appreciated...

Welcome to the forum!

Are you bound to those dimensions for the room? Are you able to make the room narrower, or wider? This is to avoid some certain low frequency modes. Try to use the golden ratio. https://odometer.org/misc/ht/

Not bound to the dimensions, it's still only partially framed so I can adjust much of it. I'll reconsider it using those, thanks! Any alterations to consider if I do stadium seating?

Yes. You don’t want a boomy box like structure underneath the seats that will resonate at some PITA frequency(s).
Brace it well.
Don’t know where the room is, can the seat bases be made of concrete?

Basement. They could but I'd prefer not to - would be quite a bit of concrete. What if I built the subs into the stadium steating, I could make the horn mouth the step maybe (though that doesn't take advantage of corner loading), or alternatively leave the space all open instead of boxing it in?

Lots to ponder at this stage lol.

No don’t put the subs there, unless it turns out with testing that that’s the best place for them to be.
Setting up truly based on sound rather than aesthetics should be your goal, but most people set up based on pics of what everyone else is doing, and that rarely works for sound.

That’s all down the track though, what to build, and building them, needs to happen first...

+1 to what Grant posted. With the subs, you should do the "sub-woofer crawl" to find the best subwoofer location(s). This is something to keep in the back of your mind as you go along with the planning.

I want each channel capable of hopefully 140db+ from 80hz up at about 10' away.
In that case you'll need 5 of these:

Your ears will quickly give up the ghost though from trying to reproduce the sound level of a firework rocket that flew in through the window. And I thought I was crazy running Omnitop 12 in my room! I mean a Marshall stack is "only" 125dB
