^Spiable, I did exactly what you are doing last Aug. Passport in married name, and my Drivers license and plane ticket in maiden name. I crossed the border and flew from Seattle to Kauai and back. They accepted my Cdn DL as my ID at both airports.
I brought my marriage cert just in case so that I could tie in from my passport to my ticket, but I had zero problems at either airport using just my DL. Obviously that doesn't mean that you won't but I think if you have your DL, passport, and marriage cert you are in pretty good shape.
ETA - I was curious and did some checking. Taadaaaa!!! Cdn DL is officially acceptable. http://www.tsa.gov/travelers/airtravel/acceptable_documents.shtm Acceptable IDs include:
