Try : pugetsoundflyfishing.com He has some good patterns on there. I like clousers and slim polarbear streamers for the needlefish and for bulkier flies like herring I go with decievers. Coho that are eating in the open salt tend to be voracious and not that picky but put them close to their natal streams in the fall and it's a whole new ballgame.
As for pinks smallish pinks streamers are your best bet.Just a size six or eight hook , a tinsel body and a pink wing of the material of your choice. I have a box full of different fancy patterns and I rarley do any better than the fishers that keep it simple. But sometimes if the pinks a pressured throw something in green or blue and it can make a difference.
