You may also want to become familiar with Next Adventure in PDX. Those guys are holding periodic pelagic seminars regarding catching those things in your back yard (so to speak).
Last seminar I went to was at Hogs JoMar Tackle (362 SW Oak St, Hillsboro, OR 97123 Phone
971) 245-6284) they have "everything" you will need to catch salmon. Lots of info at that store and the people who frequent the place are often kayakers and very easy to speak to.
