So what temperature do you guys use to solder ground wires to the back of potentiometers, I've always had trouble with that, it always took forever to get hot and solder, usually didn't stick and I always worried about burning up the inside....
I would skip that step for the reasons you mention and make grounds to the ground lug.
For the shielded runs, make a pigtail lead by wrapping a piece of thin wire around the exposed shield braid and soldering.
Use toothed washers on the pot bushings to make good contact between the pot case and the chassis.
In general run your tip temperature hot, I set my WESD51 at 700F.

I ordered a new 290FX transformer and some other parts that I want to replace because I've soldered and unsoldered them so many times they look like crap now.
Parts should be here later this week...

Got my new transformer and a bunch of new parts, I bench tested the transformer.... I've got a solid 6.5 VAC across the heater wires, that's what I need!!!!
So the build begins again, good luck to me, I've done research, watched videos, how to build, how to dress, what to watch out for...
I'm smarter than I was b4, it's gonna work this time.....
