Breaking in new parts
So, I have a fresh trans and rear differential going in. How in heck do you guys break stuff in? It's gonna take me forever to put 500mi on this thing!
Do you guys actually daily the cars until you put all the mileage on?

TRE gives break in instructions. 5 heat cycles of about ~15 miles of mixed driving. Keep it under 55-60mph for the first 100 miles. After that, drive it easy out to 500 miles. As stated, freeway cruising is not ideal, you want varying loads and speeds. And for the trans, you want the synchros and all the gears to break in, so street driving is ideal.
Changes fluids after the first 1000 miles, and then again at the 5000 mile mark.

Pick a nice sunny day and drive to Sacto and back on 5.....that'll put almost 400 on it. Of course daily it would be the way to go. Works the gear box with the new synchos and does loading and unloading of the bearings and surfaces.

Freeway is a big no no. I have to keep the diff at low speeds at first.
I read all that. It's gonna be tough because I hardly drive the car. The first change @ 500 miles will take god knows how long. After that , I'm good because it takes 2-3 yrs to put on 5k miles (kidding. I change annually).

So you complained about spending $1500 on getting a proper diff built, and now you seem to be seeing how to work around the break in instructions from the person who built the diff.
I'm sure this will end well.

2. It doesn't hurt to ask. Assuming Jon builds diffs for race cars, I can't imagine they drive around town for 500mi, so am wondering what they do. Things maybe aren't always what they seem.

Race car drivetrain parts get broken and or refreshed often. If you want it to last, follow his instructions.
