Narrative:

ATC had issued a revised routing to iah due to thunderstorms. First fix of new routing was adm (ardmore). Readbac was confirmed correct by ATC. I, as first officer and pilot monitoring, was reading bac new routing to captain who was entering data into FMC. I had the high chart out reviewing and trying to confirm 3 letter identifiers for the navigation points. Distrs were many, including a flight attendant in the cocpit telling us of a situation with a passenger in coach, crew studying WX radar, a busy ATC frequency, trying to watch the captain programming the FMC. During this time, the aircraft was in a left turn which I assumed was turning to the heading of our first fix. By the time the aircraft rolled out on an easterly heading, ATC told us to mae an immediate right turn to a heading of south and at the same time were told to mae an immediate descent to 3000 ft. During this time we received a TA from TCASII. The best I can recall after this happened, ATC reconfirmed our clearance to first fix adm which we proceeded to with no further problems through completion of flight. We were not given any phone numbers to call. The captain commented that he had programmed adm incorrectly.
