Yes. There's an issue/pull request to improve our previews at
https://github.com/ckan/ckan/pull/1251, allowing a single resource to have
multiple different previews (called now resource views). It's still work in
progress, but we've already created a few extensions using it, like
github.com/ckan/ckanext-basiccharts and github.com/ckan/ckanext-mapviews.

Yes, it's possible using the IRoutes plugin interface. Check the docs at
http://docs.ckan.org/en/latest/extensions/plugin-interfaces.html#ckan.plugins.interfaces.IRoutes
and
an usage example by the DataStore at
https://github.com/ckan/ckan/blob/master/ckanext/datastore/plugin.py#L226-L230
