I wanna make sure that I'll be able to restore all backed-up partitions using Time Machine and not only my startup partition.
This I don't know I don't use it, it doesn't make sense for TM to backup more than one partition, as a partition is essentially another "drive" to a computer, just that it resides on the same physical piece of hardware.
Far as I know TM only backups up the one OS X partition, just like a clone does.

1 Old System 9 partition that I've been keeping for years. It mostly consists of documents & apps for archiving purposes
1 partition with my iTunes Music
And of course my OS X Lion startup partition
I won't go into the specific as to why I keep my music on a separate partition but it works better for me this way (it is backed up and synced with SugarSync across 4 Macs)
All partitions are HFS+ if I'm not mistaken.
Ok, I'll explain something about the iMac's. Unlike MacBookPro's, MacPro's and even Mini's, you can't get that hard drive out or replace it on your own.
The iMac's have a heat problem, Apple has placed proprietary connectors or something on the drive on newer models that even if you had someone that could open it and replace the drive, the machine won't work. So that means really only Apple can replace that drive, and the prices they charge your likely better off after 3 years getting a new computer. 🙂 Something to think about.
So I understand the reason for perhaps iTunes being on it's own partition, but perhaps you should consider having the System 9 files on a external hard drive instead. And you should be making optional bootable clones of OS X partition, because that might become your new startup drive in the future.
CCC and Superdupes both have scheduling ability, so it can keep the bootable clone updated.
Apple will allow one more partition to be carved out in Disk Utility as long as there is space at the bottom of the OS X partition for it. If you don't want it anymore it's a real snap to get rid of it, no need to erase and repartition the drive like you would need too with three partitions.
This will give you ultimate flexibility and no mind numbing complications with three partitions.
All you have to do is open Disk Utility in Lion, click on the partition tab, click the little plus sign and size the second partition to what you need, then select a HFS+ format for it and click Apply. Simple as pie.
To remove the second partition, all you have to do is click on it, click on the little minus sign and then click on the Lion parittion and use the corner drag thing to reclaim the space and click Apply.
You can play resizing the second partition all you want in case your needs change.
With a triple partition setup, your stuck having to remove everything and resetting up the partitions and returning everything.
So that combined with the fact that if the iMac drive fails, it's going to take your System 9 data with it, and be much more work, I'd say go for the two partitions and a external drive instead.
