So far so good and does sound as if bleeding is the only bit left.
I'm going to suggest something different as this is something you need to get right rather then read a list of instructions and not take it all in.
Post up a link to the one man bleed kit pls, let's check if it is suitable or if there is a better one to look at.
Break down how you intend to bleed the brakes into simple instructions, a bullet list.
We can then comment.
Doing it this way will help get it firmly in your mind, telling others how to do something, really does make you understand it better.
If we need to, we will put up instructions but try writing them yourself first.
When you get the brake fluid, make sure you get a 6 sided (Hex) socket to suit the bleed nipple (what you called a breather) or a hex ring spanner.... I think it's 8mm but check me on that.
Over time they can get tight and are brass.
Very easily rounded off... the six sided socket or ring gives you the best chance of loosening them.
Unless you already have one
