I then package this script by itself into an update.zip -- and flash whenever I decide to flash a new ROM.

I've uploaded a faux/sample update.zip file -- unzip it and open the update-script inside /come/google/android/ and copy and paste which apks you want to remove from my script -- then after that, you'll need to zip the package back up and sign it.

Yup. Removing SDSA will not cause any problems whatsoever.

The duplications probably should be fixed, however this will not cause any issues. The system will attempt to delete the file, even if its already been deleted and not complain.
