Getting classic running on G4

I will preface by saying I have only owned a mac for about 3 weeks now.

Here is my G4 DA specs:
PPC 733Mhz 256k/1MB
1024MB ram
60GB WD hdd 8MB cache
ATI Radeon 32MB AGP
Belkin USB2.0 PCI
zip 250
DVD-R/-RW
PNY 8GB attache (connected internally to the belkin)

I have Retail 10.4.6 DVD, and OS9.0.6 CDs
OS9.2.2 is installed on the PNY, but I cant get it to boot to it via "startup disk," it will only boot to 10.4.11. If I pull the WD, it boots to 9.2.2 just fine.
When I installed 10.4, i did not do the OS9 thingy, so I am aware I may need to reinstall 10.4.

I have Sim City 3000, but the instructions say it is only compatable with OS9, or via classic mode.

If I try to hook up another IDE drive as a slave, I get the blinking mac/question mark thing.

Does anyone have a link to a step-by-step guide to getting classic mode up and running?

Reinstall will be the go and make sure when the drive is formatted the check box for OS 9 drivers is selected. If that has been chosen you can simply install side by side or partition the drive and boot holding down the Option key to choose the startup partition.

I decided that it was too much work to get SC3 working. I am running sc4 on OSX just fine. thanks for the tip though!
