NM, AniDB has these helpful graphs that tell you which parts of a series come first in relation to the story. I've never watched the Ghost in the Shell series but according to the graph, you should really watch the original Ghost in the Shell movie first (notice its not one of the ones subbed by KAA) and then watch Innocence, a direct sequel to that. After you watched those, you can then watch the Stand Alone Complex series which apparently is an alternate setting for the original Ghost in the Shell. Hope I could help.
