The firmware required is here:
Power Macintosh G3 (Blue and White) Firmware Update 1.1 Power Macintosh G3 (Blue and White) with SCSI (I could not find, remove any SCSI card before using Tiger or Leopard) The installer disk must look like:

And not say Upgrade, Dropin, a Mac model, or OEM. Once you have 9, you can get 9.0.4, 9.1, and 9.2.2 updates through the iinet link mentioned earlier.
Firmware updates and other OS 9 updates are on the following links for reference, but the iinet is where the downloads are still available.

Under 10.5 you cannot run any sort of OS 9 or "Classic" mode (unless you use SheepShaver). However, if you can go back to running osx 10.4 or lower, then you can use classic. OS 9 is probably not downloading because you're in 10.5.
