Definately bolt-on/bolt off. Spring for the Craftsman flare wrench for the lines, and go ahead and get speed bleeders for the flush and you'll be fine. I even put Speed Bleeders on the ABS Actuator, but can't seem to find the receipt (that would tell me the size to use) at the moment.
FYI, the best price I found on a new master cylinder was at
http://www.importedcarparts.com for $148.49 (p/n N3000-52312) - but that's only about $10 cheaper than Infiniti of Scottsdale. Back in 2002 I got it for $117 - guess they figured out that it was way below the dealer price for the same part.
