DUDE!! How is the ti ? ?
What all has gone wrong/broke or needed to get fixed?
Here is bunch of info from when I was looking at doing the exact same thing:

http://www.318ti.org/forum/showthread.php?t=24547 As to your questions, your correct in that you need to use the z3 rotor, the caliper from ti will bolt on, just like I currently have z3 rear caliper bolted on, so those are changeable, but the rotor isn't.
Did you look at the SRS rear adaptor?
https://srs-concept.com/product/e36-...e-adapter-kit/ They also have an adapter that allows for m3 caliper/rotor, but you loose your ebrake.
The ebrake cable will probably not be long enough, I know that was a problem before for others but I am not sure how they solved the issue. When I get home I can search a bit more, but I don't know the answer off the top of my head.
Oh btw I really miss that 3.46 diff, if you want a 3.15, I can trade you
