All you *need* is "swap" and "/".
I just suggest using a separate "/home" in case you want to wipe your basic installation and reinstall without messing up any user-specific settings/data.
The rest of those don't need separate partitions normally. A "guru" might want to tweak and fine-tune his system using them, but most users have no such need.
Edit: contusion: The purchased
version has 4 CDs. OFFICIAL Edition has 3 if downloaded.
But in any case, it is just optional apps. Nothing required to get a system up and running.
