[Q] removing stock apps correctly (busybox and terminal emulator) topic

Alright, so checking up the system folder with root explorer I noticed that there are several applications related to the stock music player.
I can't just simply remove these "apks", right? Pretty certain there'd be leftovers of this app somewhere.
So, I realize, there's no "uninstall" script for the music app, but I was wondering, what is the most correct way to delete music application?
Simple doing this won't cut it, right?

Code:

---

su
cd system/app
mount -o rw,remount /system
rm -r MusicCommonUtility
rm -rMusicLiveShare2.apk
rm -rMusicPlayerWT.apk
mount -o remount,ro /system

[Q] BusyBox Installing and Uninstalling topic

Hello,

I'm thinking of installing BusyBox on my Nexus 7. The device is rooted but before I go through with it I have a few questions about it.
Is it safe to install without having a NANDroid backup or custom recovery?
Will it be possible to uninstall without wiping the device?
What is the best app to install it? Stephen (Stericson)'s BusyBox or JRummy Ppa Inc.'s BusyBox installer?

Thanks.
