There are reasonable places to live north of Boulder. I recentishly moved out to the Gunbarrel area (technically still Boulder). The Bolt and at least one of the 200-something buses run out here. It's about a 11-15 minute drive to get to campus, and the traffic isn't too bad.
You could also look at Niwot and Longmont.
I emailed them about the issue with the right margin, asking if they could take a corrected copy as my submission, since this didn't actually give me any unfair advantage. Got this response:
So apparently they actually know this is an issue with Google Docs.
I just realised that "Download as PDF" from Google Docs resulted in my right margin not being 1" on the personal background essay I uploaded, despite the formatting being correct on Google Docs.
I... don't have words. I'm totally fucked, aren't I? When will I get a disqualification email?
