When should I apply for my citizenship?

[netra0]

Hello,
The date on my Green Card shows as March 2003. Is this the date that I have to consider when applying for my Citizenship?.
Can I apply for Citizenship this December ( ie Dec 2007) when I am 4 Years and 10 months or in Feb 2008, when I complete 5 years.

Another question:-
If I file my application after 4 Years and 10 Months, Would INS process them immediatly or will they wait till I complete 5 years before processing them.?

Thanks in advance.
