The way I did it was I hooked the SSD up by itself on SATA 0 (this way the system reserve files dont get placed on the HDD by accident and cause headaches later). Set the bios to AHCI use the install disk to format the drive because it will align the partition right, and install WIN7. Make sure you use the sata ports that are controlled by the intel chipset not the marvel. After windows is installed update to the latest Intel sata raid driver. http://gigabyte.com/products/product-page.aspx?pid=3646#dl.
I know you are not using raid but it is not just a raid driver. As for your HDD you can run it off of the marvell sata ports or the intel ports it doesnt matter although I have had more luck with my SSD running off of the intel and the HDD and CD/DVD burner running on the marvell. I am using a Gigabyte P55-UD4P.
Here is a good Windows 7 SSD tweak guide. Use it it will help prolong the life of the drive and increase the performance a bit.http://www.computing.net/howtos/show/solid-state-drive-ssd-tweaks-for-windows-7/552.html
