So, my first question is: How well will Garageband run on a 600MHz G3 with 256MB RAM? I'm pondering upping it to 640MB, but I want to make sure it'll make a big difference before I purchase the extra memory. How well will the system run in general (OSX 10.3) with the G3 600MHz processor and 256MB memory?

Next, if I want to upgrade my hard drive, is there a program that can image the OS and all of my programs like there are for Windows, or do I have to get an OSX CD and reinstall it myself?
1. The first version of Garage Band from iLife "04 will work in 256MB of RAM and on a 600 MHz G3:

iDVD will not work, and you'll need a DVD drive to install Garage Band.
2. To clone your Mac HD to an external FireWire hard drive from this computer, you'll need an earlier version of SuperDuper! The cloning capability is free in SuperDuper!. If you pay the $28, you'll get more features.:

If you don't have a FireWire hard drive, you won't be able to boot from it to this computer.
3. A 512MB memory module (which will give you 640MB total) for this computer is $59 plus shipping from:
