The bootpack is just a collection of kexts and tools, it can be copied anywhere to the install partition on your boot USB.
You copy the patched config.plist to your OSX's EFI partition (you need to enable hidden partitions in the Disk Utility), which you can edit with TextEdit since it's only an XML file.
After doing that, use HVT to install the Clover Configurator and use it to generate a new smbios for your hackintosh.
