First of all, are you deploying WebApplications to MWS?
If you want to deploy to a different container you should look into OPL (Open Presentation Layer) which is a new MWS 9.0 feature.
You can always modify the Wizard generated task portlets. As far as managing the redirects, by default the task results portlet (inbox) will create a link to the details portlet. You can change this configuration by setting some different properties on the inbox portlet:
taskDetailsPage
taskDetailsPortlet
And set those properties to the aliases of whatever page and portlet you want to use for your details portlet.
Hope this helps. --mark
