Replying to Stevens pass camping questions

Im looking into car camping at stevens for 4-5 days at a time in the next few months and i have a few questions

-If i park in the lot across the street by the shack will any one bother me? Especially snow plows in the morning, will i be in their way?

-Whats closer Skykomish or Leavenworth?

-Does Skykomish have a grocery store of some sorts? If sure Leavenworth does, where are they?

-How late are the lodges at Stevens open? Especially the bathrooms? (i need the hand dryers to dry my gloves and such if your wondering)

-Do i need my windows cracked when I'm sleeping? i always get yes's and no's so I'm not sure

-Is there a public microwave anywhere?
