Motorola Droid : How To Remove Facebook - Twitter And Visual Voice Mail

Don't know much about ROMS, kernels, etc but I managed to root my Droid last week thanks to theoverclockr instructions. I took it from stock 2.1 back to 2.0.1 via RSDlite, to 2.1 rooted, loaded the Android 2.2 and the 1.2 ghz kernal. Works great.

Here's where my questions start:

Everyone talks about Bugless Beast like its the best thing ever so I want to try it. I assume I can install that at my current state and not lose everything plus still be running 2.2 froyo?

I am guessing this is how I do it, please tell me if I am correct or not -
1. Turn my phone on in recovery, select android, then backup.
2. Download Clockwork Mod
3. Chose Flash ClockworkMod Recovery
4. Download BB4 and save it to the root of my SD card
5. Restart phone in recovert, select Wipe data/factory reset
6. Select Wipe cache partition
7. Install zip BB from sd card
8. Reboot

Now, IF that goes right, I am assuming I will still have everything, apps, etc from before just a different Rom? Whats the exact difference anyway between stock 2.2 Froyo and BB4?

If that goes wrong, I assume I restore my backup? I'm guessing you do that through recovery too?

Question #2 - What is the battery widget/app that everyone has on here that still displays your battery in the status bar but has a number % of charge in the battery?

Question #3 - Can anyone give me a simple guide on how to remove Facebook, Twitter and Visual Voice Mail. I see everyone talking about tying in commands, removing this and that but I have no idea what program to use to do this, where to do it, etc.

Question #4 - With SetCPU, it looks like with my 1.2 ghz kernel, I can underclock it back to 600 or whatever I want? I am also assuming that I can have the min and max at 1200000 and have it super fast but a battery hog?

Question #5 - Where do I get this benchmark/quadrant score everyone talks about to see how my phone stacks up to everyone elses?
