Ok, I'll try this time.
First, there is "BootCamp Assistant" - the app that sits in your OS X Applications / Utilities folder - all it does is partition your drive so that you can install Windows and be able to boot to both OS X and Windows.
That 3.0.1 you have, that is "BootCamp Assistant". You will only use this to partition the drive and start your install of Windows.
Second, there is "BootCamp" - the .exe - the driver package for Windows so that all your hardware works in Windows. It would not be installed until after you install Windows.
The 3.2 version you're looking at, that is "BootCamp"... the drivers... it will not be installed nor updated, until after you install Windows. You don't need Windows drivers if you don't have Windows installed.
So, there are 2 (two) things here. "BootCamp Assistant" - the app in OS X that partitions your drive and enables you to install Windows and "BootCamp" - the driver package you install after you have installed Windows.
