As to route, I'd check WSDOT. They have current pass conditions, and web cams. Stevens Pass is highest and more likely to have fresh or compact snow. Blewett is almost as high, but overall drier. From Issaquah, I think I90 and 97 are more direct. Driving north to US2 could be slow, though they have added more 4 lanes on the leg from Woodinville to Monroe.
