What's the 1k resistor for on DB3 in the data bus between the LCD and microcontroller in the Monochron schematic? I looked in the datasheet for the display and saw nothing.

It's because the microcontroller pin is shared between the LCD and the programming interface. See http://ladyada.net/make/monochron/design.html for more info.
