Very few of the PPCs ( your g5 ) will recognize an external usb dvd drive. You need an external firewire dvd drive.
Try holding down the option key then power on. This brings up the startup manager. Click on your hd. Click on right arrow key.
Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:
"The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

If you have a second Mac computer, you may want to try to copy over as many files you can. One way is to use target disk mode.

Thanks for the reply! Unfortunately, it didn't work. I'm not able to reset my PRAM, at least through the method you described. I only get two chimes total before it opens to the screen with a question mark. I was able to reset NVRAM and open Open Firmware - but I'm still not seeing any drives in Startup Manager and cannot boot from CD. I tried booting from the CD drive in Open Firmware as well, but to no avail.
