Check out this guide to Seattle, all by locals:
There is a large section on shopping (under "explore"). Restaurants are under "Necessities."
I really enjoyed the Underground Tour. On Sunday check out the Center for Wooden Boats, which offers free Lake Union sailboat rides on a historic wooden boats, Sundays at 2 pm. You may also rent boats (sail & paddle) by the hour (after a brief skills test). 1010 Valley Street, 206-382-2628. Or take a lakes cruise-- you can see the Sleepless in Seattle & Bill Gates's houses.
Chateau Ste. Michelle is on the east side, about 30-40 minutes to downtown, although from Lynnwood it might be less.
There is a Sur la Table in Pike Place. You can ride the monorail to/from downtown (the market is downtown) to the Space Needle.
Just so you know, Everett & Lynnwood are a good bit outside of downtown, I'd say at least 20-30 minutes. And downtown is about 20 minutes north of the airport.
That's all I can think of right now. I'm sure someone else will chime in.
The role of a librarian is to make sense of the world of information. If that's not a qualification for superhero-dom, what is?
