Which size drums on 69 Dart? And some other brake questions.

I was just checking the repair receipts and the rear shoes and drums were replaced 4000 miles ago (that was 2011). If I replace the shoes 1) should I do all the other hardware, like springs, adjuster, etc.? 2) Do I need to turn the drums after so little miles?

At the times, in 2011, everything was replaced on the front, including the cylinders. I noticed the mechanic said the flexible brake tubes on the front (I guess that means between the cylinder and the hoses) were cracked and replaced. If I don't see any leaking or cracks on the flexible tubes on the rear is there any reason to replace them?

Also, any brands for the brake cylinders that are considered good quality?
Unless the drums are grooved, warped, or worn funny, I'd just reuse them the way they are. No point intaking metal off them if it isn't needed. The rear will just have one hose, from the center of the body to the top of the rear axle housing. I'd replace that if it's original. The hard lines are anyone's guess at this point. If they aren't nasty/rusty looking, and fluid passes through them ok, I'd reuse them as long as the flare nuts are still in good shape. If you replace them, I'd get regular steel lines unless you're in a bad rust area, then I would probably go stainless. If you can find any NOS American made cylinders, I'd go that way. First, I would hone out the originals to see if just a kit would do the trick.
