Using a Web Service Task that writes the results of the call to a file may enable you to get started using SSIS 2012 instead of staying in SSIS 2008. You could then use an XML Source in a Data Flow Task or the SQLXML Bulk Load tool to load the files to staging tables in a database before applying the data to the final destination.
There are no special teachers of virtue, because virtue is taught by the whole community.
