I used WinToFlash to clone a Windows CD to a USB to make it bootable.
Is there a way I can push Windows Updates to the USB so WU does not take as long to run?

Your best method of achieving a bootable windows install with updates already installed is to create a custom version of the installer. Its possible using third party tools such as WinReducer.
There is a tutorial/example here: http://www.howtogeek.com/169522/customize-your-windows-8-installation-disc-and-slipstream-updates-with-winreducer/
