The stickers without a white circle are for safety & emissions, and the ones with the white circle are safety only. Cars that are 2 years old or newer, older than 26 years, historical, or (some) diesel get the safety inspection only.
As far as I know inspection stickers are good till the very last day, but I recommend you go in the begining or middle of the month to avoid lines from everyone else that's waited till last minute.

A NYS Inspection sticker expires on the last day of the month it was punched during the year indicated on the sticker. If the sticker says "2011" and the month "June" is punched, the vehicle needs to be re-inspected on or before June 30, 2011.
