Hi,
It seems like if you are going to build a regular stud wall inside the strawbale wall you might be better off to just go with the double stud wall and use lots of cellulose fill in the the middle.
Not sure why you would want to use the drywall inside? The plaster finish walls I've seen in strawbale homes look outstanding (to me).
Lots of info on strawbale and double wall construction here:

One of the books thats listed:
Building One House: A Handbook for Strawbale Construction, Nathaniel Corum
is very very detialed on strawbale construction.
Lots of construction detail.
