Christopher,

Take a look at:

MacDonald, P.L., & Gardner, R.C. (2000). Type I Error Rate Comparisons of Post Hoc Procedures for I j Chi-Square Tables. Educational and Psychological Measurement, 60(5), 735-754.

García-Pérez, M.A., & Núñez-Antón, V. (2003). Cellwise Residual Analysis in Two-Way Contingency Tables. Educational and Psychological Measurement, 63(5), 825-839.

Cox, M.K., & Key, C.H. (1993). Post Hoc Pair-Wise Comparisons for the Chi-Square Test of Homogeneity of Proportions. Educational and Psychological Measurement, 53(4), 951-962.

Seaman, M.A., & Hill, C.C. (1996). Pairwise Comparisons for Proportions: A Note on Cox and Key. Educational and Psychological Measurement, 56(3), 452-459.
