OK, in addition to the ones you've listed...
-The first person to enter your home in the new year should be a man, otherwise it is bad luck
-Do not put up a new calendar until New Year's day - - - again, bad luck
-However you bring in the new year, is representative of how you will spend the majority of the following year. So, in the company of friends...then so be it in 2006. Sloppy drunk, then so be it in 2006...
