I have used AutoSPInstaller on quite a few 2010 Foundation installs and I have never needed to modify the script files. If you just remove the references to services it does not use AutoSPInstaller will skip those steps.
I did look at your blog and I really would not make most of the changes you are instructing. The script is very intelligent, "Thank you Brian, I love this thing", by changing the PowerShell script you are potentially making it more difficult to keep up with new version of the script.
If you don't like how a function does something, try copying the function to the AutoSPInstallerFunctionsCustom.ps1 file and modify them there. AutoSpInstaller will use the functions in that file over the functions in AutoSPInstallerFunctions.ps1. This will help you when a new version comes out.
I'm just saying.
