congratulations on quitting smoking, i know how tough it can be. i did the nyc 5 borough century last year on my track bike and stopped for four cigarette breaks, this year i'll complete it as a non smoker.

my gearing was 48x18, there was a lot of stopping and starting so i was glad i kept it at an easy gear. i also rode with toe clips because the route went through the city (a lot of roadies we're getting frustrated with having to clip out every other block).
