SATA driver needed for new OS install

Hello, I installed Windows 7 and I'm in the process of installing drivers from my motherboard's manufacturing website. I have a P5QE mobo (https://www.asus.com/Motherboards/P5QE/#support). I already boot in AHCI mode.

I have already installed the following 4 items from the site:

Under the Audio Section: SoundMAX 2000B Audio Driver V6.10.2.6585 for Windows 64bit Windows 7.(WHQL)
Under the Chipset Section: Intel(R) Chipset Software Installation Utility V9.1.1.1019 for Windows 32/64bit XP & 32/64bit Vista & 32/64bit Windows 7.(WHQL)
Under the LAN section: Marvell Yukon Gigabit Ethernet Driver V11.10.5.3 for 32/64bit Windows 7.(WHQL)
Under the SATA section: Marvell 6121 SATA Driver V1.2.0.69 for 32/64bit Windows7.

I noticed that there is another download under the "SATA" section.
This download contains the items:
Intel(R) Matrix Storage Manager Driver V8.9.0.1023 for Windows 32/64bit XP & Windows 32/64bit Vista & 32/64bit Windows 7.(WHQL)
Intel(R) AHCI/RAID Driver Disk for Windows 32/64bit XP & Windows 32/64bit Vista & 32/64bit Windows 7.

Do I need this download? I do not run in RAID.
Also, I've heard that IMSM 8.9.0.1023 causes windows issues like disabling windows updates (https://communities.intel.com/thread/29057)

Also, are there any other drivers I should be installing (I've already installed my video card one, and all available windows updates). I also did not install my chipset driver first (it was the second driver I installed). Would not installing the chipset one first be an issue?

Thanks in advance!

*Edit: I also have this already in my device manager
Not sure if this means I don't need the driver in question though.
