Hi George,
Partition the drive, it will make for ease of pain.
Try this partition sceme.
7.5GB 1st partition for OS 10.2 install, or make it even smaller if you like, but not larger.
2.5GB 2nd partition for OS 9 install
10 GB for programs
10GB for documents
The last two are preference, it really is up to you how big or small you want those two.
You will not need any other special software like X-Post Factor or such to install Jaguar on a Beige.
There is no firmware upgrade for the Beige G3 to install OS X. The firmware upgrade mentioned by Marcel is for the Blue and White G3.
You can not install Jaguar on the drive on another computer (your G4) and then run it from your beige, it (OS X installer) will configure OS X system for that specific computer and it's hardware.
Make sure you have the drives jumper settings at Master, not master/single or slave. What model Maxtor hard drive do you have? On their web site you should be able to find the schematics for the jumper setting, but it should have come with the drive too.
