Uninstall Stock Apps on Motorola Droid!
Cyanogenmod has a barebones list of apps and the relative safety of uninstalling each.  While it's for CM ROMs, the list will be pretty similiar for the DROID.

FYI, if Verizon ever releases any OTA updates in the future for your phone, they won't install if you don't have the stock apps installed. Usually you're better off 'freezing' them with Titanium Backup.
