1. Root it
2. BACK UP YOUR APPS
3. Pray to god (and by god, I mean motorola. ), that you don't get stuck in a bootloop the next time you try to put the apps back on, or install a system update.
Otherwise, you could just install some launcher which allows you to hide the apps you don't want.
(Oh, and don't come complaining to me if your phone dies).
If you use LauncherPro, you can just hide them. It's not like removing them is gaining all that much more space. Remember, this phone has a ton of app storage.
