IMO, the ROMs available at the moment aren't worth the trouble. Bootstrapping is just a method to get into recovery to flash a ROM, or run a backup or another functional ROM in case you find yourself in the unenviable position of a boot loop. If you have root, and you want to remove unwanted applications, then simply download a terminal application from the market. I suggest Terminal Emulator. It's free and gets the job done. Then open up the emulator and type
Code:
su
mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
cd /system/app
mv nameofapp.apk nameofapp.bak
mv nameofapp.apk nameofapp.bak
mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
exit
exit
after each line, hit the enter key to execute.
Of course, you replace "nameofapp" with the actual app name. Like typing Skype_mobile.live will change the name of Skype. You could use the rm command(rm Skype_mobile.live) to remove it altogether, but I would just use mv to be on the safe side so there are no complications if another over the air update becomes available. This method insures you won't have to worry about it appearing in your app tray, or having it run in the background(not that I think it does anyway)To see a list of all the application names, after typing cd /system/app [enter] then type ls [enter]. That will give you a list of all the applications. For example, the amazon app is amazonmp3_1.7.22_signed_zipaligned.apk.
I hope that helps. I would advise against messing with any of the Motorola apps, that includes backup assistant. Kindle, City ID, Blockbuster, Need For Speed, My Verizon, or the 3G hotspot app are all fair game.
