Driver confusion. Which is bloat?

Hi, I have an AsRock Extreme4 Z77 motherboard & 2600k on its way. Looking at the drivers to install, a lot of them seem like bloat. Is it necessary/useful to install all of these? The INF, LAN, SATA3, and USB drivers are the only ones that look like I'll actually need to install, but I wanted to check to be sure. To add to that, which USB driver should I be installing? Also, where are the chipset drivers? All of the intel "features" (junk), seem to be pointless for a desktop. The CIR driver is for things such as wireless presentation tools and the like, correct? The rest of my build in my sig will be incorporated into the new system to give point of reference.
