Hey CC - I just received in the mail today a DVD called Performance Mountain Biking by Ned Overend that I ordered after a recommendation by SadieKate. It goes thru braking in lots of different situations even deep sand (hmm this could come in handy for you in WA). This might also help you out with your query of what to do in Pea Gravel.

If you cant get a copy let me know and I will try posting a little of the info for you. Watching the DVD is heaps better though then reading a blurb.
