If your contacts are all saved in Gmail, you can access them through the website. There will be an option buried somewhere on the contacts page to export the contacts to a CSV file. This file can be imported in your My Verizon account for contact backup.
Although I do question why you need to do this.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
Thanks for reaching out. I know how important it is to transfer your contacts. If you already have the contacts in your GMail account, once you plug your GMail account in your Droid 3; they will carry over. Ann154 is also correct about the CSV file and then saving it to your computer and then uploading it to My Verizon under the Back Up My Contacts page. I am sure everything will work out for you.
