I recommend connecting ONLY the SSD to install Windows. If you have any other drives connected then Windows will try to create a "recovery" partition on one of the other drives - that will be the actual boot partition. Most people want the boot partition to be on the same drive as the OS, hence the recommendation to leave the other drives disconnected.
The most important thing to do is to make sure the BIOS is set to AHCI mode (and not "legacy" or "IDE Emulation" mode) before you install. If you do that then you should be able to add the other drives and load the RAID drivers once you've got Windows 7 up and running.
Caveat emptor: I haven't actually set up RAID this way, but I believe it should work. However if someone with real experience has another recommendation then you're probably better off following their advice.
