I am currently running OS X 10.3.9 on my iMac G5. It came with this operating system as well as 512MB of RAM and I had them add another 1000 of RAM when I bought it. I have lots of software that runs in Classic (for example, Photoshop 7) and I read that Leopard (OS X.5) will not support Classic software. I have 3 questions:
1) can I upgrade from OS 10.3.9 straight to OS X.4.11
2) will I be able to use iWork '08 and iLife '08 if I do? and
3)What precautions should I take before and during the upgrade?

Thanks in advance for all your help.
