FOTH is an excellent book. Especially if you are going to get into more of the mountaineering side of things. Which being in the PNW, I don't know why you wouldn't.
Another book that I would recommend picking up is the Avalanche Handbook. It's sort of dry, but it is the Freedom of the Hills for avalanche professionals. It covers everything. Worth having on your shelf.
Bruce Tremper's book is tops. Good choice on reading it. Take a level I after reading it and you'll be very happy.
