Triple boot, dual drive Macbook i5, iso/usb

Hi guys,

I spent most of my evening yesterday using Mroogle/Google to figure out how to get this done, but for the life of me I can't get it to work. Here's my setup;

Macbook Pro 2.4 i5
drive bay 1 - 60GB Vertex II
drive bay 2 - 320GB Apple HDD (using Optibay)

Here's what I'd like to do;

drive bay 1 - Mac OSX + Applications
drive bay 2 - Mac OSX data storage (290GB) + Windows 7 (20GB) + Ubuntu (10GB)

The tools I have;

- multiple Macs
- multiple 4GB USB sticks
- Windows + Ubuntu .iso files
- Support software like Parallels / rEfit etc.
- No working Superdrives/CD-combo :-(
- LAN network

I tried using Bootcamp, but that didn't go well as it won't let me install from USB-stick. I tried installing through Parallels (as suggested in MR forums), but I can't use it because Parallels 6 won't recognize the Bootcamp partition. I tried rEfit, but can't get it to work because I can't restore the .iso files to the USB stick (I have no working CD/DVD unit) using Disk Utility.

Please help me devise (or find) a strategy to get a triple boot, dual drive system so I can take over the world

Any suggestion is welcome

ps: if you need any additional info, or if my question is not clear enough, please let me know
