No.  Bleeding eliminates air bubbles due to opening the lines (after
caliper swap, etc.).  Flushing runs new fluid all the way from the
master to the brakes, essentially bleeding until the fluid runs clean.

Anti-seize to try to rust proof the bleeder screws, containers to stop
excess fluid from making a mess.

One bleeder at a time, just a half turn or so.  Then pump, I do it
gently and not all the way to the floor.  It may only take 5-10 pumps to
bleed, more to flush.  You just keep hopping out and running around to
the bleeeder to look at what is coming out the clear hose.

No.  Tires can be on.  It's just easier to see with them off.  I would
recommend it if you haven't done this before.  An extra set of eyes (or
pedal foot) can be a great help here too.

sure.  but if they're bad they usually break in place!

No, just back it up a half turn or so.  fluid will probably begin to
drip a little at that point.  Remember, you need to be able to tighten
it afterwards reasonably quickly, with the bleeder tool hose still
attached and full of fluid.
