You start with the wheel furthest away from the master cylinder (measured by length of brake tubing) and work toward the closest. The side you steer from isn't critical.
I'll take a guess that it's going to be the left rear that you start with, then right rear, left front, then finish with right front.
I would say you need one big bottle of brake fluid, or two small.
Depending on the age of the braking system, you may want to have a few extra bleed screws on hand.

do you have any idea which size bleed screws are on these things?

Autozone had a few different sizes:

M7-1.0
M8-1.25
M10-1.5
3/8”-24

You can call Rovers North and order them and they will be guaranteed to fit, or order a generic M10x1.0x1.25" bleeder. Your call.

They are metric and you need an 11mm wrench on them
