Forest,
Well, o.k. get ready to take notes.
I'm guessing that you are targeting Coho (Silvers) and maybe a Chinook (King) Salmon.
We have been putting the hurt to those Coho critters with Delta Divers and hootchies. I like the silver prisim delta with the flashibou trailer. The half red half prisim is also hot here in Oregon and will probibly do alright in Washington as well.
For the Kings we have been using the Rotary Salmon Killer,

You can learn how to rig up at this URL...
Hot Salmon Rig
For bottom fishing you can use any big heavy jig and a few Shrimp Flies. Check with the regulations for the area you are fishing to see how many hooks you can use. Double hookups are not uncommon and you could luck into a Ling Cod, Cabizone or even a tasty Halibut. Again, check the regulations and make sure you are legal before harvesting any fish.
You will also want some bait. Herring or Sardines for the Salmon. Check with fishermen in the area to make sure you get the right size. It sounds like your buddy is dialed in so he should be able to help with this. Get gresh bait, it makes a difference.
Good luck and give us a full report when you get back.
Mr. F.
