If there has been a thread about this already, I apologize

I'm picking up a used Treo 700w as a replacement to my Samsung flip phone this friday and I know how to transfer numbers online at the Verizon site from phone to phone (I've done it before from my LG to my Samsung)

Do I need to do anything else when transfering a new number to a used Treo 700w phone?

any info, links, or help is gratefully appreciated

Also is 50 bucks a good price for a used Treo 700w with a few scratches?
