memory
Since you cannot access the SDRAM chip in the iMac, get that with a 512MB chip. Then go and get a good chip (SODIMM, PC133). Don't get generic memory, but stuff that is guranteed to work with your system. I do know that all the memory sold by Mohawk Memory has a lifetime gurantee on it. You want to make sure that the memory vendor that you use has a similar policy in effect (and in writing). To make it a little easier, check out their prices for memory for the iMac G4 700/800 Flat Panel.
As for partitioning up the hard drive, I wouldn't bother. I have every system that has OS X installed on it with a single partition. Every tech within the company I work for is running it with a single partition (with both OS 9.2.2 and OS X 10.1.5) without any problem at all. We will be rolling out OS X to all the Mac's within our company with the drive as a single partition (well over 1000 Mac's). Some people seem to think that having multiple partitions will benefit them for one reason or another, I have yet to see any real justification for those claims. In the end, make your own decision, just don't blindly follow someone that claims that partitioning up your drive and moving things all over the place will make things run better/faster/smoother.
