No there is no tutorial for using Spry Auto Suggest with Dynamic Dropdowns.
The Auto Suggest component will really only be able to be applied to the main parent list, since the data for the child lists is populated dynamically based on the selection of the parent list.
The major hurdle to overcome will be creating the DataSet for the Auto Suggest wizard to use, you will need to manually create a page to loop through the database table for the parent list to create an XML data set.
