In terms of the bleeder kit, it needs 'at least' 2 bar, so keep it around 2.5 to be sure. I just keep an eye on the gauge as I bleed it, and then pump it back to 2.5 for the next one.
Instructions start on page 110 of the following PDF:
17-Service Manual Brake system.pdf
There are instructions immediately after this about the brake master cylinder. If there's any possibility of air getting into the ABS unit, there is VCDS procedure for bleeding that through the front left caliper. If running this procedure, make sure there is plenty of brake fluid in the pressure bleeder, as it runs for 10 seconds.
