What's the best way to install new cedar shake siding on a Craftsman house built in the 1910's?

My garage burned down in an arson fire a few years ago and the cedar shake siding on the rear of my house was burned to a crisp (thank fucking Christ the house didn't burn down, the original home builder knew his shit.) I've had it stripped of the cedar shakes down to the boards for five years now with just a shitty layer of Tyvek wrap on it to protect the boards, but I'm so tired of it looking like a shit-stain and rain and wind damaging the exposed board. Is there anything in particular I need to know before I start? Is there a particular brand of cedar shake I should get? Do I need to replace the boards now because they've been exposed to the elements for so long? The framing around one of the windows was damaged and scorched pretty badly, so how do I deal with that?
