Whoa there. Take a deep breath. I know those Honda dashes are tricky. I took apart the dash to install a new head unit in my 2001 Honda Accord and my roommate's 2001 Honda CRV. Not the easiest dashes to pry apart.
My best resource was handaaccessories.com. They provide PDFs of OFFICIAL HONDA install instructions for honda factory stereo components. There are step by step diagrams on how to disassemble the dash. Hopefully these are more useful than the Crutchfield instructions.

Good luck.
