Paul, There is a nice paper by Raghunathan that compares different methods for how to handle probability samples in MI (i.e., fixed effect vs random effects models). I have had good success by using fixed effects for clusters within strata and running separate MI models for each strata. This is contingent on having an adequate number of observations in each strata. I have not included sampling weights, as inclusion of strata and clusters should be enough to preserve relationships between different variables.
