Depending on the size of the dataset you want to bring over, you could use the query tool on the REST page to get the data in JSON format and then use FeatureSet.convertFromJSON method to add to your application.

I do this for some small sets of data for testing purposes. It won't be feasible for a large dataset though, just too much info to parse.

Hmm, not sure about that one. The Map Service REST would pull the geometries for you. If you are not using an MXD, you'd need to write a Web Service of some sort using ArcObjects to get accesss to those geometries. Haven't tried that specific scenario though.
