Good luck.
1st HDD: 320GB - OS drive

3rd HDD: 750GB - storage
4th HDD: 750GB - mirrored storage for 3rd drive
How should I partition my drives?
320GB is pretty big iron for an OS drive, you'll have a lot of space left over
for programs / data, though you'll want to be careful because Vista does eat babies (oops I meant hard drives) when it gets very upset.
Should I create a small-ish 20GB partition on HDD1 just for Vista OS (no programs, no documents, no swap, etc) and have the second partition, which will be the rest of the 320GB drive, devoted to programs and documents, and have the swap file on another HDD entirely?
20GB is too small for a boot partition. I had to resize a 40GB C: to 50GB just to have a FEW GB left over, and that was without a page file or much any software installed on that partition.
Since you have a big drive, I'd say make C: 70GB, put the pagefile and hibernate file on C (there's no choice about the latter), and install "system" software like anti-virus, firewall, data recovery, whatever on C: also.
Lots of applications will, whether you like it or not, install part or all of themselves to C: even if they can install a "lot" of their files to D:, E:, whatever. So allow at least 10GB for such applications that work better on C: or don't work otherwise.
Also for defrag to work well you need at least 25% free space on your C drive, so that should be what you have left over at all times, probably around 15-25GB free.
Keep in mind all the system restore points and temporary files, temporary internet files, and your user profile (Desktop, "My Documents", "My Music", etc.) will also be on C: and a lot of Vista software really EXPECTS your downloads / documents / etc. to live within your user profile on C:. Internet Explorer is a big case in point.
You'll burn through several gigabytes of restore points, temporary files, uninstall files, etc. just installing SP1 in a few weeks.
You never want to be in a position of saying "oops" I need more space on C: since even with a partition resizer it'll be painful or impossible to fix without a SLOW process.
If I do this configuration, if I ever need to format the 20GB Vista partition, will I lose the ability to use my programs on the 300GB partition after reinstall because things like the registry will have been nuked?
Yes, you'll lose access to all your programs, this sucks royally. Please tell the fine people at Microsoft this and maybe one day they'll change this "C:" and "Registry" insanity. If we tell a program to install to "D:\Somewhere" then that's EXACTLY where it should go, and if you reformat C:, Dual-boot into another OS, whatever, the program should still be usefully installed on D: where you left it. ALMOST NO program installation will survive a dual-boot or reinstallation of C: even if it didn't install any files on C: just registry data etc. Sorry.
For the partition after C: I'd make one that's just a bit bigger than C: then you have a quick place to image-backup your C: to; not a replacement for copying it to a physically distinct drive for secure backup, but a good quick place for a weekly snapshot or something. It'll also be an easily expendable buffer-zone you could delete if you had to expand C: by resizing it to fill into this area.
Then use the rest of drive 1 for program installations and data and such.
The pair of 750's in a RAID is a nice setup for online storage, though probably wasteful if you only occasionally have to get / put files to them. This is just because Windows is pretty rock-stupid about spinning drives down so unless you're very careful and lucky in setting them into suspend mode, they'll spend a lot of the time powered on and idle or spinning, neither or which is ideal for their operational lifetimes if they're really only needed for a couple of hours per day or less. In many cases for offline storage putting them in a cheap 2nd PC that you can turn off independently
makes some sense.
Then again maybe with some power-tools you can get Vista configured to let those drives to into soft-power-down standby mode after an hour or idle time and not wake up every minute for no good reason...
