I checked at gmail and it appears that IMAP is the way to go. My only
question would be reagrding the incoming and outgoing servers. All my
existing email comes to my my original ISP (mail.vgernet.net). Can I
keep that as the incoming ISP and use the SMTP as gmail or must I do
something else.

Why use gmail's IMAP if you don't intend to ever receive. Change your
existing Comcast account to point to gmail's SMTP server. Do not change
your email address. Enable authentication of the outgoing server. Select
the "Log on using" option and specify your gmail credentials. The mail's
sender will be your Comcast address, but it will be sent via gmail's server.
