I have a 6 am flight out of SIN (T1) and am wondering what is open at that hour and how early to arrive.

Arriving one hour before your flight is plenty, unless you or your plane are going to the US.
Changi never sleeps: all the basics (cafes, food court, most of duty free etc) will be open, although some boutique-y shops may still be closed.

The standard check-in policy would do.
I believe starbucks would be opened, the dfs would be opened and the 24 hour lounges of course.
