Yes, you can get all the threaded bits from your local brake centre, but you could reuse your old ones and use new line. You'd just need a double flaring tool, which aren't expensive from ebay.
The copper nickel bends really nicely, and you don't need tools to bend it, whereas you would by using steel.
I'll be needing to do this all very soon on Cam's series 3, so I'll be chatting to a Vicroads approved engineer, and my local mechanic who does my road worthies before I buy anything. I'm hoping the copper nickel will pass as its heaps easier to work with.
