If you haven't done so, install Titanium Backup. This makes it easy to remove bloatware, such as any pre installed games, or anything with your carrier's label on it., e.g VZW Tones would be safe to remove. My rule of thumb is that if it has the 'Droid icon (how it's displayed in Titanium) next to it, don't mess with it. Titanium is also a lifesaver if you ever get into flashing ROMs, as it allows quick reinstall of you favorite user apps.
