I found that HTCGreader.apk is responsible for the NEWS application constantly updating in the background.
I had to re-enable Pico tts to regain voiced turn-by-turn directions in the Navigation app.
I nixed VVM.apk, which I thought was responsible for Visual Voicemail, but it's still running on every re-boot and has to be killed manually.
Nixed NabService.apk as well. Not sure what it does, but everything seems to be working okay without it.
Can't find the Dragon Dictation app, but my guess is that I need that for giving voice commands to my phone. Either way, I'm very pleased with my rooted phone which seems to be running faster without all the bloat. And, for the record, I just used the renaming .apk to .bapk method after rooting, so as not to accidentally delete a necessary file.
