Dear Mike, an excellent paper exactly concerning your problem is
Raghunathan, T.E., Grizzle, J.E. (1995). A Split Questionnaire Survey Design. Journal of the American Statistical Association, 90, 429, 54-63. Another paper with a similar approach (but not splitting in advance) is Gelman, A., King, G., Liu, C. (1998). Not Asked and Not Answered: Multiple Imputation for Multiple Surveys (with discussion), Journal of the American Statistical Association, 93, 443, 846-869. Hope that helps.
