One of the things you can do to help propagation speed up is to set
the time to live down on your existing name servers so that people
cache them for a shorter period of time(you will have to have ait do
this though).  Also update your name servers with your registar on a
Friday at close of business most of your propagation will happen over
the weekend when no-one cares, at least it will be the least impact
especially on mail.  Remember to not have the short time to live on
your new servers at it will add unecessary queries to your domain name
servers.
