I'm replacing the front nose on my 2002 myself and was wondering whats the easiest way to get this thing off?

You have to take off your fenders to get your nose off, or atleast take the bolts off the front so you can gently move the fenders out of the way to get the nose off. My friend and I did an entire wide body on his C6 and this is what we had to do on that. I know that yours is a C5, but I am sure that the concept is still the same.
