Personally, I never partition more than I have to - if I have one disk, I use one partition and run everything off of that one partition. That's the most flexible way (since you won't overflow any partitions before you fill the disk). I boot Mac OS 9 and Mac OS X from the same partition (not that I've booted Mac OS 9 more than once in the last year). I generally keep a large file or two (usually images of game CD-ROMs I own) to delete just in case I need the ballast. The only reason I can see to partition a disk these days is to prevent filling one partition from affecting another - so if you download a lot of stuff, for example, you might want to download to a distinct partition. In the bad old days with unstable filesystems, it was a whole 'nother story, but now... nah. But if you have your reasons, go for it. The only downside is that down the road you might end up wishing that you had done otherwise. Of course, external firewire disks are cheap enough that you probably won't have much difficulty fixing the problem if you need to.
