Wow,
Seems like an impressive feat to undertake, no doubt. I haven't spent much time there, so I have no useful info, but seems like a great area according to the accounts of the late Supreme Court Justice, William O. Douglas, whose had spent much time there. One of my favorite books is Of Men and Mountains.
The Pacific Crest is defintely a good idea too, try "The Pacific Crest" by Shaeffer or Schaffer.
