I don't know if you already have the parts, but if you need them I just had a kit from Blauparts put on my car and it literally came with every part you'll need and is all OEM sourced.
I went with the enhanced+ kit and couldn't be happier.
I bought the kit for $320 and had a shop do it for me for $350. I'm not in WA though. Try these guys, they seem to have good review, call em up and ask for a quote: http://www.yelp.com/biz/volkswagen-specialist-buttera-motors-kirkland-2
