Partitioning for my new hard drive

[Pi rules]

I'm lost about how to partition my new hard drive (320 GB Seagate SATA II) and what to do with my old (120 GB WDD PATA).
I would like to have several Linux distros on it (Ubuntu, SUSE, maybe Xandros, Fedora, etc.) so I would need a FAT32 partition to exchange files.

Does this sound feasible:
320 GB:
1. NTFS Windows XP system partition - system files and programs, paging file (~10 GB)
2. NTFS Windows XP data partition - data, videos for video editing (rest of drive, ~290 GB)
GRUB boot loader

120 GB
1. NTFS Vista system partition - system files, backup for #2 of SATA drive (~60 GB)
2. FAT32 exchange partition - (possibly with Windows 98 for experimentation) 10 GB
3. ext3 Ubuntu partition - 10 GB
4. ext3 SUSE partition - 10 GB
5. ext3 Xandros partition - 10 GB
6. ext3 Fedora partition - 10 GB

Does this sound like a decent formatting option? My boot loader will be GRUB, probably from SUSE or Fedora. Also, would the paging file be better placed on the SATA II drive? It would be faster, but I don't want that HDD accessed too much while video editing. As mentioned, I do some amateur video editing, so I'll need a good deal of storage on a fast drive. I thought about installing XP on the PATA drive, but that might not help much and just slow down the boot speed.

That looks fine to me...but I would leave paging file on same drive.

Actually, I think ext3 might be better; it allows online resizing. Last time I tried to shrink a ReiserFS partition it corrupted the Linux installation.

OK, thanks. :wave: (posted at the same time). I'll edit my original post to fix these two.
Edit: Which partition do you think would be best?
