I don't know about AD part but looks good. Consider also the MAX1452 - is very good conditioner, PGA, filter, etc for strain gauge. Is missing ADC, but choose a good micro that has ADC on-board and you have complete system. Maxim has evaluation board with PC interface, very easy to try out.
I forgot to mention that you must have a ratiometric connection to the strain gage.
I.e. that you have the same reference voltage to feed the strain gage as to the ADC.
This because any changes in the voltage would cancel it other.
Linear technology has also various app. notes about strain gage interfaces.
