You don't need to necessarily remove components to make lite. As some components are changed from Vista to Windows 7, i think you will be better by starting to learn about Windows Automated Installation Kit and how to make a proper Autounattend.xml file to customize your setup. Then, start by making registry tweaks and tweaking services. Starting by removing Windows 7 components will likely increase the chances of errors, un-bootable installations, BSOD's etc... When nuhi (vLite's author) gets more input on components, then you can strip your setup.
