How much brake fluid do I need for flushing?

[speedyspaghetti]

Hey guys! I'm planning on bleeding my brakes and clutch in a couple of weekends. I have a motive power bleeder on the way ($41 on Amazon - great deal) and a bleeder bottle.

Correct me if I'm wrong, but as far as I understand it the process goes:
1. Jack up car
2. Remove wheels
3. Open brake fluid reservoir cap
4. Attach power bleeder to reservoir and pump to 22 psi
5. Bleed passenger rear, driver rear, passenger front, and then driver front brakes
6. Bleed clutch

My questions are:
1. How much brake fluid do I need? It's my understanding that if the power bleeder runs dry I'll have to start all over again, so if I have too little, I'm screwed. Would 1L be enough, or should I get 2 and put them both in to be safe?
2. Is ATE Dot 4 (Part #: 000-043-203-66-M4) the correct brake fluid for the car?
3. Any other helpful tips/tricks that could help me? This is my first time attempting the job.

Thank you!
