If it were me I'd likely forego the use of the PCIe card interface and just connect it to the Intel controller. Using the stand-alone PCIe card you will probably lose TRIM capability and your boot time will be longer (if either of those matter).
If you connect it to the Intel controller there isn't much you need to do. Windows 7 will have a native AHCI driver that will get the rig up and running. Windows 7 will also properly align the SSD during formatting and installation.
You'll want to make sure that your storage controller is set to AHCI in the BIOS.
After Windows 7 is installed and updated you might consider installing the Intel RST driver - but that isn't a necessity.
