What up with this SBC bill message?

It does sound very suspicious. The only way I'd think you'd be receiving SBC bills on the Internet is through their eBill service, which is located on their site and which you'd have to log in via a secure server to access. I seriously doubt they'd be sending you any of those bills via e-mail. Maybe receipts for payment of said bills, sure (and in the actual e-mail message too), but not the bills themselves.

Also, messages from a "Lori Brown," related to the SBC messages, and unrelated.

(I don't have any account with any SBC thing-y to begin with, so I guess calling it very suspicious was an understatement.)
