Here's a list of apps that I've removed, so far without consequence:
Sorry, the list is a mix of APK names that I manually removed, App names that I have frozen in Titanium, and package names that are backed up and uninstalled also via Titanium. I later found out that system apps cannot be restored from Titanium, so I've resorted to removing them from /system/app manually.
You'll notice that a bunch of the Bluetooth stuff is removed, because I don't use Bluetooth at all. Your mileage may vary.
