Where are your PDFs? Are your PDFs on your SD Card? Up at the top of the home page of ezPDF is a button labelled 'All PDF' and that should list PDFs on your sd card. If you then tap on it it will open, if you tap-and-hold you have the option to move it to ezPDFs folder on the sdcard. I'm not a heavy ezPDF user so don't know if there are other tricks to opening PDF files from within the program.

However, it sounds like another PDF program is set as the default. You can remove this behavior by opening NookColor Tools, selecting 'All Settings', "Manage applications", then finding your current PDF reader in the list, tapping it, then tapping 'Clear defaults'. Then when you next try to open a PDF file (say by using a file browser such as Astro) it should ask you what program you want to use and you can choose ezPDF. Odd, though, usually when you install a new program it clears the defaults for you.

Also, if the stock Reader is your currently set PDF default, you might not see it listed at first in NookColor Tools. If you don't, then hit the menu button, select Filter, and make sure 'All' is checked.
