Resolved
I previously had the problem that I was getting the warning message -> com.motorola.service.main has stopped unexpectedly. (I also have been experiencing a problem with adding more than 2 Gmail accounts (see other post).
com.motorola.service.main More information:
I previously indicated that when I went into "Setting"s and then "Accounts", I would almost always get that error message and a Force Close tab. I have since realized, however, that I would also occasionally get that error message when I had the Droid's "Mail" application open. I never received that error message any other time (than in Mail or in My Accounts).
Resolution of issues:
So after trying to resolve these issues by working within my setup, I decided to return the phone to the original factory settings.
Settings -> Privacy -> Factory Data Reset.
This of course wipes everything off the phone. When the phone was in the process of rebuilding, I decided NOT to go with any form of the Motorola's Backup Assistant. I then proceeded to enter in my Gmail accounts. With the original phone/ first time through I had indicated a Gmail account, but had clicked on the Droid's "EMail Accounts" icon in the Set Up Accounts window. This time I thought about it more and realized (duh) that Gmail is a Google type of account. So this time I clicked on the 'Google" icon in the Set Up Accounts window. I did this for Gmai1, Gmail2, and Gmail3 accounts without any problem. And all three Gmail accounts got entered under the Droids Gmail application (so when I click on the Gmail app, and list the accounts, it shows all three Gmail addresses as I wanted. I next downloaded the K9 email app (which I highly rec over the Droid's Email app). I next added my work email address to the K9 application. I NEVER opened or used the Droid's "Email" application. My phone now works flawlessly, and no more com.motorola.service.main error/shut down messages. Boy this phone is fast/nice!
So my phone hardware was good, its internal configuration, however, was the problem. I would suggest, if you are having problems with your new phone to go ahead and do the factory reset and try the setup again. The reset takes ~5 minutes, setting up your email another 5-15 minutes. Less time than trying to call or bringing your phone to your carrier.
