UPDATE: I decided to just go with one partition because it seems like less hassle. But if anyone still wants to answer my questions, it would be nice for future reference 
-------------------------------------------------------------------------------
So I replaced the 160GB drive in my 13" MBP with a 640GB drive. I now have the 160 in an external enclosure. I got the huge drive so I can finally copy all my crap from my PC to my MBP and have it in one place. I don't have any big external drives, so I had 2 ideas:
- Make the 640 into 100 and 540 partitions, with the system on 100, and use the external 160 with time machine (assuming that's possible with TM?).
- Make the 640 into 160 and 480, system on 160, clone the system to the external 160 regularly as a backup. This seems better since the external will then be a full working system (I assume), in case my internal drive would ever break.
With either of these, I'm wondering how easy it is to separate all my media onto the other partition, like the itunes library, pictures folder, movies, downloads, etc.
OR
Should I just stick with one huge partition, and figure out some other partial-backup solution / wait till I get a big external?
Thanks to anyone that can give advice! In the meantime I'll go spring-clean my old drives.
