You should really check sites like www.redcross.org for the usual suggestions.  They have lots more detail there.  Here is the summary version.  Note that most lists say that you need a 3 day supply.  We personally feel that you should be prepared for 1 week due to the delay of supplies to damaged areas!  Plus, you might want to donate supplies to someone in need - so you will want some extra supplies.
