Clunking Around

Greetings

I'm hoping for some advice on how to optimize my G4. More specificly... I upgrades to 10.4.11 and have loved the new features (have had OS X for years though). Origionally did a clean install. I didn't want any old files to bog down the larger system requirements. All was well. Fast and tidy. Until...

I needed to use GoLive 4. (ominous sound: dun dun dunnn)

Of course I needed classic support. After researching I found I needed to install OS 9 through 9.2.2 for optimum classic performance, as 10.4.11 doen't come with classic at all.

Done. (By the way a giant pain in the arss)

Now to the question pending. Can I dump any files from these installs to lighten up the hard drive? Everything seems to work spiffy but if I can get more all the better. I have increased ram and two internal and two external HDs. Just want the lightest load one the main drive as possible as it has the smallest capacity.

PS While I'm at it can I easily change the slave, which is larger, over to the primary? I thought about it and took it all apart only to find the pins on the back of each were different. One was missing (not broken) a pin so the configurations I assume are different for each dive to achieve slave/primary. I know this may be just researching those specifics but after physically switching them the operating systems will then be on the slave. Is it an issue?

Thanks in advance!!!
