You need to change copyright year from 2008 to 2009.
Why? The purpose of putting a date on copyrighted material is to help you know when the copyright will expire (althought it's not in your lifetime :-). If you have material that you created in 2008, but put a (c) 2009 on that page, technically you are trying to cheat and extend your copyright protection by a year.
I know, for web pages it doesn't make any sense, but you might as well know what the right thing to do (TRTTD) is.
I ask because it always feels to me, when I see "(c) 2001" or something similar, that a site is rotting on the vine.
